Ovulation calendar and the most favorable days for conceiving a child

Ovulation- this is the process during which an egg that is mature and completely ready for upcoming fertilization leaves the ovary, enters the abdominal cavity and is then sent into the lumen of the fallopian tube. It was during this period that the likelihood conceiving a child maximum and is estimated at approximately 33%, which, of course, should be taken into account when calculating ovulation calendar and a woman’s planning for an upcoming pregnancy. After ovulation the egg is capable of fertilization ( conception) for 12-24 hours, while sperm after ejaculation remain active for 2-3 (and much less often 5-7) days. Considering this fact, the possibility of a woman becoming pregnant the day before ovulation is approximately 31%, two days before - 27%, and three and four days before ovulation- 16 and 14% respectively. In the same time conceiving a child six days before ovulation or the day after it is unlikely and even practically impossible. Usually ovulation occurs between the 14th and 16th days of the menstrual cycle under the influence of estrogens and pituitary hormones.

Ovulation calendar and sign of conception

One of the most reliable and important signs of the onset ovulation and favorable period for conceiving a child are changes in a woman's cervical mucus. First of all, under the influence of estrogens, the amount of secretions increases and their viscosity decreases. The next, no less important, sign of egg maturation should be considered a decrease in rectal (basal) temperature during ovulation and raising it the next day. At the same time, in order to more accurately calculate ovulation and conception calendar, it is recommended to take your temperature every morning at the same time for several months. Sometimes at the moment ovulation a woman feels pain in the lower abdomen, the nature of which can vary quite widely from weak and short-term to strong and very long-lasting. It should also be noted that on days ovulation Some women experience a peak in sexual arousal.

Ovulation and conception calendar is a diagram of the menstrual cycle, which marks the time of its beginning, end, as well as the ovulation. Full management calendar involves mandatory recording of periods of active sexual activity. Compilation ovulation and conception calendar it is necessary to start long before planning pregnancy in order to learn how to determine the moment as accurately as possible ovulation and become familiar with all the features of your own body.

Ovulation calendar and conceiving a child

Depending on the probability conceiving a child and time ovulation menstrual cycle ( conception calendar) can be conditionally divided into three phases: relative sterility, fertility and absolute sterility. The period of relative sterility begins with the appearance of bloody discharge and ends ovulation. During this phase, some difficulties with contraception may arise, since its duration sometimes varies within several days, even with a stable duration of the cycle as a whole. This happens due to the fact that periodically, depending on certain factors (external and internal), ovulation comes a little earlier or vice versa later.

The fertile phase begins from the moment ovulation and ends after 48 hours. At this time the probability conceiving a child as high as possible. As noted above, after leaving the ovary, the egg is capable of fertilization within 12-24 hours, the remaining half of the time is allocated to inaccuracy in timing ovulation. Following the period of increased fertility, the woman enters a phase of absolute sterility, during which conceive a child almost impossible. This period lasts until the end of the menstrual cycle and is about 10-16 days.

Ovulation calendar and calculation of the period of conception of a child

Most modern women expect ovulation and conception calendar in order to bring the long-awaited motherhood closer. Others are building calendar to protect yourself from unplanned pregnancy. However, no matter what goals they pursue, when calculating the menstrual cycle (and ovulation calendar in particular) in any way there is always a possibility of error.

According to the calendar calculation method ovulation a woman should record the start and end days of her menstrual cycles for at least six months. In order to determine your individual fertile period based on these data ( ovulation and conception calendar), it is necessary to subtract 11 from the number of days of the longest cycle (the last fertile day of the cycle), and 18 from the number of days of the shortest cycle (the first fertile day). So, for example, the longest cycle for a woman is 32 days: 32-11=21 (the 21st day of the cycle is the last in the fertile phase). Her shortest cycle is 26 days: 26-18=8 (the 8th day is the first in the fertile phase). In this case, the most favorable period for conceiving a child is the interval from the 8th to the 21st day of the cycle (13 days in total).

One of the best and more accurate methods of calculation ovulation and conception calendar child is a combination of the above methods, which is called the symptothermal method. It includes measuring basal body temperature, daily monitoring of cervical mucus and accurate calculation ovulation calendar and favorable period for conceiving a child calendar method.

Action of tests for calculation ovulation calendar based on the same principle as for diagnosing pregnancy. When interacting with a woman’s urine, two transverse lines appear on it, one of which indicates the normal performance of the test, and the second indicates an increase in the level of luteinizing hormone (LH) and the woman’s full readiness for conceiving a child. However, if the second line remains paler than the control line for several cycles in a row, this may indicate the absence of ovulation due to any disease (thyroid disease and hyperprolactinemia, obesity and exhaustion, polycystic ovary syndrome and infantilism, increased FSH levels and decreased estradiol levels, chronic stress, etc.) and is a reason to consult a doctor.

The term “ovulation” itself comes from the Latin ovum - egg; This is the name given to the process of release of a mature egg capable of fertilization from the ovary into the abdominal cavity.

Physiologically, ovulation is one of the stages of the menstrual cycle. Ovulation in women of childbearing age occurs periodically, every 21-35 days - in the middle of the menstrual cycle (the cycle is usually counted from the first day of menstruation). The frequency of ovulation is regulated by hormones from the pituitary gland, an endocrine gland located in the brain, and ovarian hormones (estrogens and progesterone). Ovulation stops with the onset of pregnancy and after the cessation of menstrual function.

The most favorable time for sexual intercourse for the purpose of conception is when ovulation is about to occur and sperm have enough time to enter the fallopian tubes, where they “wait” for the release of the female germ cell, or immediately immediately after ovulation, when the egg is already in fallopian tube.

Day of Conception

If you correctly calculate what day ovulation will occur and have sexual activity during this period of time, then there is a high probability that the woman will become pregnant.

So, how can you determine ovulation? First of all, using subjective signs. This may include short-term pain in the lower abdomen, a feeling of a “bursting bubble” in the middle of the cycle, some women note an increase in sexual desire - this is due to the release of estrogens during ovulation - female sex hormones that are produced in the ovaries. Some signs can be detected during a routine gynecological examination, although it is difficult to imagine that a woman who believes that she has no reproductive problems will consult a gynecologist just to determine ovulation. However, a woman can notice a number of signs herself.

The day of ovulation can be determined by observing the secretion of mucus from the cervical canal. The maximum secretion of mucus is associated with a sharp increase in estrogen levels and coincides with the moment of ovulation. In addition, sometimes the stretchability of mucus is used, and its crystallization is also observed. During ovulation, the mucus becomes very viscous, it can be stretched between the fingers up to 8-10 cm. The more pronounced the crystallization, the greater the likelihood of ovulation. This phenomenon is most clearly manifested 3-4 days before ovulation and reaches a maximum on the day of expected ovulation. Crystallization is the result of biophysical and biochemical changes in the cervical mucus. During this period, there is an increase in the amount of mucus and an increase in the concentration of salts, primarily sodium chloride, which, along with potassium ions, is responsible for the phenomenon of crystallization. With pronounced crystallization, mucus looks like a fern under a microscope. There are special microscopes for home use that you can apply mucus or saliva to. The main changes occur precisely in the vaginal mucus, but they also affect the entire body, so for convenience they began to work with saliva, in which it is also possible to determine the symptom of crystallization. The action of the Baby Plan ovulation detection device is based on this phenomenon.

The next most accurate and informative method for determining ovulation is measuring basal temperature - the temperature in the rectum. The method is quite simple and does not require virtually any special equipment other than a regular medical thermometer.

Basal temperature is measured with the same medical thermometer in the morning, immediately after waking up, without getting out of bed. The measurement must be carried out at the same time, inserting a thermometer into the anus to a depth of 4 - 5 cm. Temperature measurement data is plotted on a graph, the vertical axis of which is the temperature, and the horizontal axis is the day of the menstrual cycle. The chart also shows days of sexual intercourse.

For many women, careful monitoring of the basal temperature chart can reveal that before the temperature rises, there is a short drop in temperature. According to this method, it is believed that the moment of ovulation occurs 12 hours before the increase in basal temperature or between the decline and the beginning of its rise.

Is it possible to choose the gender of the child?

When planning a pregnancy, few potential parents do not think about how to choose the gender of their unborn child in advance. Some need a boy, others need a girl. Such planning becomes especially relevant when the family already has one child. As a rule, parents dream of having a second child of the opposite sex.

There is only one way to more or less scientifically soundly try to plan the gender of the child. A sperm with a male set of chromosomes moves faster, but lives shorter than a sperm with a female set. Therefore, the coincidence of sexual intercourse with ovulation (about 14 days before the onset of menstruation in a 28-day menstrual cycle) increases the likelihood of having a boy, and the birth of a girl is more likely if intercourse occurs 2-3 days earlier. However, this rule does not always work, since it concerns the classic situation of parents who are “super healthy” in all respects. If one of the partners has health problems, this, as a rule, affects the “speed characteristics” of sperm. For example, this happens when the acid-base balance of the genital tract is disturbed or the qualitative composition of the secretion changes in women, or when physical fatigue occurs in men (it also affects the mobility of the “livelings”).

But all these listed methods give only approximate results. Their accuracy makes it possible to determine the moment of ovulation only by using all of them in a comprehensive manner and with fairly long-term observation. What allows you to accurately determine the moment of ovulation and guarantee it to be documented? Strictly speaking, there are only two such methods.

The first is ultrasound monitoring of the growth and development of the follicle - the vesicle in which the egg matures, and determining the moment of its rupture - ovulation itself. Often, with the use of modern devices, it is possible to see even the moment of release of the egg, if the study is carried out at the right time.

The second method is the dynamic determination of luteinizing hormone in urine (this is also an ovarian hormone, the amount of which increases during ovulation). This method is much simpler and can be used at home, for which special tests are used. Tests begin to be carried out 2 times a day (every 12 hours) 5 - 6 days before expected ovulation, strictly following the instructions attached to them. The determination is stopped after receiving the first positive result. Ovulation occurs approximately 16-28 hours after the first positive test result. To control, you can immediately conduct another test. The most convenient and informative use of tests for luteinizing hormone in conjunction with measuring basal temperature. Dynamic determination of luteinizing hormone was previously used only in specialized medical institutions, but now there are test strips, the same as for determining early pregnancy. Such tests are sold in pharmacies. Thus, the problem of determining the moment of ovulation should be considered practically solved.

It must be said that if there are no alleged problems with conception, then you can start with a simpler method - calculating your ovulation based on the duration of the menstrual cycle. To do this, as we have already said, the duration of the menstrual cycle must be divided in half. You can start “working” on conception, taking into account the fact that some sperm live up to 7 days, a week before the expected ovulation, the favorable period will end 3 days after ovulation.

Keep in mind that pregnancy may not occur immediately during the first “dangerous” period, because... Even healthy young women have 1-2 cycles a year in which ovulation (the release of an egg) does not occur.

In addition, ovulation is affected by stress, climate changes, etc.

Conception position

After you have calculated the most favorable days for conception, you must avoid douching, any soap and similar products after sexual intercourse. Firstly, the very fact of washing contributes to the mechanical removal of sperm, and secondly, hygiene products create an environment in the vagina that is unfavorable for sperm. And before sexual intercourse, you should take a shower in advance (30-60 minutes) so that a normal, natural environment can be restored in the vagina.

Couples who want to conceive often wonder: is there a special position they should use? It's safe to say that any position acceptable to both partners will do. After sex, it is better to lie on your side or with your pelvis elevated for 15-20 minutes to prevent sperm from leaking out.

We hope that our tips will help you move into the category of future parents as soon as possible.

The vast majority of women know about such a thing as ovulation. But not everyone knows how to calculate the timing of its onset. There are several ways to help you find out the cherished date in each new menstrual cycle. However, the easiest way to do this is to use an ovulation calculator: it is better to calculate the most suitable days for conception with its help.

To get the result, you must enter the date of the first day of your last menstruation, the duration of the menstrual cycle and bleeding. You also need to indicate how long the calculation is required. As soon as the data is provided, you will be able to see a graph indicating the expected dates of menstruation and days favorable for conception.

- Ovulation

Favorable days for conception

Hello dear blog readers. If one of you is not fully aware, why do it at all? I'll explain. The fact is that for fertilization this process plays an almost dominant role. You need to know the date of egg maturation in order to effectively protect yourself from an unwanted pregnancy, or to obtain this pregnancy. However, often “mere results” are not enough. That is why we will analyze in detail why and when the egg leaves the ovary, how to accurately calculate ovulation using different methods.

Physiological aspects

Ovulation is the process of the release of a mature egg from the ovary. This happens under the influence of neuroendocrine mechanisms at different levels. This term means that nerve impulses and hormones play a role in this. Without going into details, let's look at what happens in the body.

The menstrual cycle is counted from the first day of the previous one until the beginning of the next menstruation. As soon as the bleeding ends, the next follicle begins to mature in the ovary, containing a germ cell - the follicular phase of the ovarian cycle begins. Gradually, with the development of the egg, the level of sex hormones increases.

By the time the follicular formation finally matures, the female body has a peak level of estradiol (the most active subtype of estrogen). When this value is reached, the walls of the follicle begin to collapse - the ovulatory process begins, triggering the luteal phase. As soon as the reproductive cell is “free,” it is sent to the fallopian tube, where it is able to live for 24 hours, waiting for its sperm.

In place of the torn “receptacle” of the germ cell, the corpus luteum matures - this is, relatively speaking, the “yolk” that will nourish the fetus until the placenta is formed. If conception does not take place, then the egg dies, and the corpus luteum regresses as unnecessary. Throughout the entire period of its “life,” it produced the hormone progesterone, which is designed to help the fertilized egg implant (introduce) into the wall of the uterus. It softens the endometrium (the inner lining of the uterus), makes it loose, and improves blood supply. But with the regression of the corpus luteum, this hormone becomes less and less. And the loosened epithelium can no longer become “tight” again. Therefore, as soon as the level of progesterone decreases critically and the level of estrogen increases, another menstrual bleeding begins - rejection of the uterine epithelium.

So, ovulation is the release of an egg from its “shelter”. This “action” occurs approximately in the middle of the cycle (for example, if the latter lasts 28 days, on the 14th day). The release of the germ cell from the follicle can take place on the 13th and 15th day, this is considered normal. But the fact is that that same corpus luteum always lives only 14 days (rarely ±48 hours), regardless of the duration of the cycle. This means that if it lasts 35 days, then ovulation will take place on the 21st day, and if it is 22, then on the 8th. An ovulation calculator can calculate the optimal date for conception based on these data.

But what to do if you have an irregular cycle? When one time there are five weeks between bleedings, and the other time it is three weeks? In addition, there are such concepts as early and late menstruation, which are deviations from the norm, but occur frequently. How do you know when the time is right to start getting pregnant?

Calculation of ovulatory date

There are many methods to help find out exactly when the reproductive cell will mature and be released. Among them:

  • online ovulation calculator (calculating the appropriate date for conception is the easiest and fastest), essentially repeats the calendar method;
  • temperature method;
  • cervical method;
  • symptothermal method;
  • by ultrasound.

Test Methods:

  • test strips;
  • inkjet tests;
  • using a microscope;
  • "fern" method.

It should be noted that to achieve reliability of any of the listed methods, it is necessary to carry out measurements for at least 5-6 cycles. You can compare what data the calculator provides and how the body actually behaves.

Calendar method

In principle, it has already been described in the previous section. It can only be used by those women who can boast of having periods “just on schedule.”

Observation must be carried out for 6 “circles”. You need to keep a menstrual calendar, clearly marking the start and end dates of bleeding. For analysis you need:

  1. Identify the longest cycle. You need to subtract 12 from its length in a day. Why this particular number? As already mentioned, the corpus luteum lives only 14 days. For the reliability of calculations and taking into account possible physiological variations, it is worth slightly “expanding” the possible period of its appearance. This will be the last day in this cycle when conception can take place.
  2. Find the shortest cycle. Subtract 19-20 from the number. The calculation is as follows: for example, the cycle duration is 26. Of these, 14-15 are the luteal phase. This means that ovulation occurred on day 11. However, sperm can live in the vagina for 2-3 days. Thus, starting from 8-9 days and ending with 12 are days favorable for conception.

Basal temperature measurement

Basal temperature is the “warming” of internal organs in a calm state.
It is necessary to measure the temperature:

  • in the rectum (acceptable - in the vagina and mouth);
  • at least 5-7 minutes;
  • daily (including during menstrual bleeding);
  • at the same time;
  • immediately after sleep, which lasted at least 3-5 hours;
  • with the same thermometer.

In the follicular phase of the menstrual cycle, the temperature does not exceed 36.4-36.8°C. However, 12-24 hours before the separation of the egg from the follicle, it rises, sometimes by almost a degree! This occurs to stimulate the rupture of the follicular formation. And throughout the postovulatory period until the first day of the next bleeding it remains at a level of 37.1-37.5°C. The period of time from the beginning of the cycle until the third day after the temperature jump is considered fertile.

This technique is used mostly for contraception rather than for pregnancy planning. After all, ovulation is often “visible” after the fact, when it has occurred. And after the third day of rising temperature, pregnancy is not possible until the next cycle.

However, it is best to combine the method of measuring basal temperature and an ovulation calculator - you can calculate the days for conception more accurately.

Cervical method

The vagina and cervix are very “slimy” organs. The possibility of pregnancy, local immunity, and the condition of the mucous membrane depend on the presence of this natural secretion. The condition of cervical mucus greatly depends on the level of hormones in the body. The more estrogen, the more liquid the secretion. Immediately after menstruation, it is almost gone, which is unfavorable for sperm. Then it appears, but thick, viscous, like glue. It is inconvenient for male reproductive cells to move through it; they feel like they are in a swamp. Gradually it becomes more liquid, and by the time of ovulation it is watery, slippery, reminiscent of egg white. Here they swim straight to the uterus.

Symptothermal method

The most reliable of the above is... a combination of these methods. If you calculate the release date of the egg according to the calendar, monitor the temperature and the state of mucus for several months, you can learn to determine ovulation almost accurately. Thus, in order to achieve conception, you need to carefully monitor your body.

Ultrasound diagnostics

Ultrasound is one of the key research methods in gynecology. With its help, you can track the process of follicle maturation from the very beginning until the release of the egg. This is done by a functional diagnostics doctor who records the size of all follicular formations in the ovaries. As the moment of release of the egg approaches, one of them should increase in size, so that it will soon rupture and turn into the corpus luteum.

If the doctor sees that none of the follicles are growing, then he is forced to state an anovulatory, “single” cycle. It is possible to diagnose:

  • hormonal deficiency (the formation has already developed, but the cell does not come out of it);
  • premature hormonal effects (corpus luteum begins to form even before ovulation);
  • cyst formation (postovulatory follicle growth);
  • and etc.

It is worth noting that the calculator is not able to provide for anovulatory cycles and failures. Therefore, if there are any abnormalities or suspicions of them, it is necessary to be examined using ultrasound.

Test Methods

Similar to tests for determining the level of hCG (pregnancy test), there are test strips for recording luteinizing hormone, which is responsible for ovulation. There are inkjet tests, as well as strips that need to be dipped into urine. They can show one stripe (ovulation is “far away”), “one and a half”, in the sense of one fuzzy (usually 2 days before and 2 days after the release of the reproductive cell) and two - “we are here”.

To use such strips, it is necessary to use the calendar method. You must first calculate the average cycle length, find the approximate date of the ovulatory process, count 3 days from it and start conducting tests.

As already mentioned, at the ovulatory moment the body contains the largest amount of estrogen during the entire cycle. To find out what the content of this hormone is, they use the “fern method”. It is necessary to apply saliva to the glass. On days when the hormone content is low, when drying, salt from the liquid is deposited in the form of randomly located points. But when estrogen levels are high (2-3 days before ovulation and 2-3 after), these points are systematized and resemble a fern leaf.


Photo enlarges when clicked

Today glass has been replaced by mini microscopes the size of a lipstick tube. It has an area for applying biological fluid, as well as an eyepiece in which the result is visible. The principle of operation is similar to the “fern” one. Interpretation is carried out using control drawings from the instructions.

Thus, you can use anything: ultrasound, test strips, ovulation calculator - calculating suitable days for conception is not a problem. It is useless to argue about which of the listed methods is more accurate: ultrasonic, of course. However, it is less accessible and requires regular and frequent hospital visits. The test method is only slightly inferior to it. However, it is best to use a combination of several techniques. What to do if the cycle “jumps”?

Irregular cycle

How to calculate ovulation with an irregular cycle? The optimal test method is a mini microscope. The costs will be minimal (one such device costs about 300-400 rubles), the “equipment” will last a long time, and it will accurately show ovulation. And if you conduct research every day, then it is impossible to miss it.

You can also use the cervical method. Cervical mucus is one of the clear indicators of approaching ovulation, and it begins to change a few days before it.

But the temperature and calendar method will be of little help, including a calculator, because even if you monitor your menstruation for a year, the calendar calculation of the date of ovulation will be purely approximate.

Conclusion

Thus, with a regular cycle, the ovulation calculator can calculate the best time for conception “at once”! To be sure that the calculation is correct, you can repeat it yourself, as well as use other methods. However, if you experience any problems with your cycle or suspect recurring anovulatory periods, be sure to consult your doctor. I hope that this article was useful to you, and I bid you farewell until the next useful materials. To make sure you don't miss the weekly newsletter, subscribe in the right panel of the blog.

There are a number of reasons Irregularity of the menstrual cycle. The main difficulty of this period is, which is very important for successful conception. does not last long and with an irregular cycle this moment is very difficult to determine. It should also be taken into account that such a cycle can be a symptom of a disease that must be eliminated before conception.

Many women have regular discharge, which means that the time between menstrual discharge is constant.

About an irregular cycle we should say:

  • A woman faces the difficulty of calculating the day of her menstruation, since it occurs at different times.
  • Menstruation of varying degrees of profuseness.
  • Menstruation varies in length: sometimes 3 days, sometimes 8.

This phenomenon not considered critical and does not require visiting a doctor (if the deviation is no more than 3 days).

Causes of failure

Unpredictability of periods creates difficulties in determining ovulation. A woman cannot calculate the day of her desired conception. The main causes of menstrual irregularity can be identified.

External problems

These include:

  • Severe stress.
  • Overvoltage of any kind.
  • Neuroses.
  • Climate change.
  • Strict diets or fasting.
  • Bad habits.
  • Irregular sex life or its complete absence.

All violations are easily explained. Before ovulation, estrogen was responsible for the functioning of the hormonal system; after ovulation, progesterone was responsible.

Domestic

These factors are much more difficult to deal with. Basically, these are diseases. Cycle disorders are caused by infectious, somatic diseases, as well as inflammatory processes in the genitourinary organs. Tumors and endometriosis may be to blame. The body during this period is weakened and cannot.

Negative effects of medications

Usually, these are hormonal drugs (not only). Because of them, menstruation is scanty and short. Incorrectly selected drugs influence its duration and characteristics of its course.

You should know that the Postinor cycle, used as emergency contraception, is especially often disrupted. Delay ovulation antidepressants and blood thinners.

Sometimes the intrauterine device is to blame. Naturally, abortions influence changes in the cycle.

Is it possible to calculate the date of ovulation if you have an irregular cycle?

When a woman has such a cycle, it is quite difficult to determine the exact date of ovulation. Calculation using a calendar is ineffective, and measuring basal temperature gives only an approximate result. Ultrasound scanning most accurately reveals the day of the desired conception, although other methods should not be abandoned.

Detection using special tests

In the female body during maturation luteinizing hormone comes to the fore. Diagnostic tests are based on its definition. Sometimes two strips are enough to get the desired result.

Necessarily attention should be paid on cervical fluid. It becomes larger, and its consistency is similar to egg white.

During ovulation, it opens wider and becomes much softer. By the way, if you place a finger in it, it will be noticeable that the temperature in the vagina has increased.

Women who actively engage in sports notice that during ovulation the body becomes flexible, and training is more effective, as you feel a surge of energy.

Increased ability to work, and the desire for intimacy also increases.

Laboratory blood diagnostics

Analysis carried out in the second phase(one week after detection of ovulation symptoms). The amount of progesterone in the blood is examined. This hormone is produced in the ovary, and its main purpose is to prepare the female body for pregnancy.

When ovulation occurs the hormone content in the blood is 0.45 - 9.45 nmol/l.

Blood is donated definitely in the morning and on an empty stomach. There should be at least 8 hours between the analysis and food intake.

Saliva analysis

Not only will they help determine ovulation. It has been noticed that if a layer of saliva is applied to a glass surface, then after drying, a pattern resembling a fern leaf appears in this place. This is the so-called arborization phenomenon. He talks about the imminent release of the egg. This phenomenon is due to the specific hormonal background of women these days.

Ultrasound

There is no more reliable way, but you will have to conduct the study for a month with short breaks. For the most accurate result, ultrasound is performed with a vaginal sensor. The study is done every 3 days, starting from the 9th day.

Reference! Only ultrasound monitoring can confirm the presence of a condition in which a mature egg is not released.

Ultrasound allows you to monitor changes occurring in. When ovulation occurs, the size of these bubbles increases to a maximum. It expands to 20 mm. Then it bursts and the egg is released.

Possibility of getting pregnant and planning the sex of the child

Fickle cycle is not an obstacle to desired pregnancy, but due to the unpredictability of favorable days, it is difficult to predict the period of conception. That is why it is impossible to predict the gender of the child. But you can try, there are certain recommendations for this.

If parents they want a boy, then it is better to have sexual contact on the day of ovulation or on the eve of this date.

This is explained by Y chromosomes move faster than X. Excessively acidic vaginal microflora negatively affects the Y chromosomes; they remain in it for no longer than 2 days.

An important role in conceiving a boy is played by contact posture. It should ensure deep penetration of sperm.

Mutual orgasm is desirable, in which the acidity of the vaginal environment decreases, it becomes alkaline. Such an environment does not have an aggressive effect on the male sperm set.

A girl's planning is different. X chromosomes are slow and can live in the vagina for more than 3 days. Therefore, it is advisable to have sexual intercourse 3 days before ovulation.

When choosing a pose, you should consider that the sperm should not penetrate deeply. By the way, female orgasm is optional. In this case, the vaginal environment will remain acidic, which will cause the death of the Y chromosomes.

The reproductive function of the female body depends on the normal functioning of the ovaries and uterus. There is one day in the month - ovulation, when a woman can easily become pregnant. With a menstrual cycle of 28-30 days, it occurs 2 weeks before the start of the next period. Women should know how to calculate ovulation in order to correctly determine the period when the egg leaves the follicle and is ready for fertilization.

How to detect ovulation

Methods for detecting ovulation:

  • using ultrasound;
  • urine testing;
  • measuring basal temperature;
  • by external signs;
  • calendar method.

The most informative method is considered to be ultrasound diagnostics. Thanks to this method, you can monitor the development of follicles, correctly predict the date of ovulation, and see the release of the egg. This method also has its disadvantages:

  • the study does not allow us to judge the patency of the fallopian tubes;
  • To carry out diagnostics, you have to visit the clinic a couple of times a month.

An unqualified specialist will not be able to accurately calculate the required day.

They do a urine test at home. Using this method, the level of luteinizing hormone is determined. A small amount is always present in the urine, but the day before ovulation the level increases. The test is sometimes uninformative. Additionally, it is recommended to do an ultrasound.

A simple, accessible and cheap way is to measure basal temperature. Every morning, while in bed, a woman should measure the temperature in the rectum. During the period of ovulation and two days after, the temperature rises by an average of 0.4 degrees. A few days before menstruation, it drops by 0.3 degrees. You can record your body temperature data and plot it on a graph to see fluctuations. If there are no ups or downs between periods, this is a signal of possible infertility.

The onset of ovulation is also recognized by external signs. Women should listen carefully to their body in order to correctly determine the day when the genitals are ready for conception.

  • increased sexual desire (non-permanent symptom);
  • pain in the ovary area, lower abdomen;
  • breast swelling;
  • copious mucous discharge;
  • emotional instability.

During ovulation, women experience increased sexual desire. This is due to the function of hormones. Nature took special care to ensure that conception occurred on the most favorable day. But a woman’s libido depends on many factors, so the sign often turns out to be uninformative.

When the egg leaves the follicle, the woman feels pain in the lower abdomen. The discomfort may last a couple of minutes or several days. But not everyone experiences discomfort. If a woman felt fine, and then began to experience pain, this may indicate pathology.

During the maturation of the egg, the breasts become sensitive. She starts to ache a little. The painful state of the mammary glands in the middle of the menstrual cycle indicates the onset of a period during which conception is possible. Breasts swell to a greater extent before menstruation.

The mucus produced by the female genital organs is a favorable environment for conception. Before ovulation, its quantity increases, it becomes viscous, similar to egg white. Changes also occur in the cervix.

Sometimes watery vaginal discharge has pink streaks, yellow or brown spots. This indicates that the egg has already been released. The cause of bloody spots is rupture of the follicle. Mucus is a sure sign of fertility. When it is absent, fertilization is difficult or impossible.

Important! A woman behaves too emotionally during the period of possible conception. She becomes irritable, gets nervous over trifles, and sometimes cries for no reason. During this period, it is recommended to spend more time in the fresh air and not overreact to irritating factors.

Childbirth has a huge impact on a woman's condition. It takes some time for the menstrual cycle to resume. In the first months, menstruation may occur, but the maturation of the egg does not occur during this period. When breastfeeding, anovulatory cycles last longer.

You can determine the time of possible conception using the calendar method. To do this, women mark the day when menstruation begins and ends. You need to record this data every month. In this way, the timing of your fertility can be accurately calculated. It occurs in the middle of the menstrual cycle.

How to calculate the day of ovulation

There is a way to calculate the day of ovulation. You need to take an ordinary calendar and regularly mark the date when menstruation begins and ends for 6 months. In this way the duration of the menstrual cycle is determined.

If the average cycle is 28 days, then the egg will mature on the fourteenth day. After 14 days, the woman will begin her period. But the egg does not mature regularly, and in some months ovulation does not occur. There are cases when a woman experiences two ovulations in one cycle. There are periods of late maturation of the egg. This is observed with concomitant endocrine and gynecological diseases, over the age of forty years.

If a woman is completely healthy, her menstruation regularly begins on the 2nd of each month, the cycle is 28 days, then ovulation will occur on the 16th. It happens that ovulation occurs two days earlier or later than the due date, that is, not on the 14th day, but on the 12th or 16th.

Calculation formula for monthly periods:

  • date of ovulation = day of onset of menstruation – 14 days.

If the duration of the cycle is 26 or 30 days, then the number of days of the cycle must be added to the first day of the onset of menstruation. This determines the beginning of the next menstruation. Then you need to subtract 14 (13-15), you get the date of maturation of the egg. With regular menstruation, ovulation occurs two weeks before the start of the next menstruation.

Important! To get pregnant, you need to have sex every two days during the ovulation period (for a week), not more often, otherwise the fertility of male sperm decreases. If pregnancy is undesirable, special attention should be paid to birth control at this time.

How to calculate ovulation with an irregular cycle

An irregular menstrual cycle is not a cause of infertility. This condition can be caused by gynecological diseases or nervous disorders. The norm is considered to be menstruation, which occurs at regular intervals (28-30 days). If you have an irregular cycle, you cannot use the calendar method to calculate the best day to conceive a child. Ultrasound provides useful information.

At home, you can use a test to determine the level of luteinizing hormone in your urine. In this case, on the 9th day after the start of menstruation with a 26-day cycle or on the 13th day with a 30-day cycle, you need to test your urine twice a day for 5 days in a row. For irregular periods, the shortest cycle is taken as the basis.

Important! When using tests, you should drink less fluid so as not to change the level of hormones in your urine. Before testing, you must not urinate for 3 hours.

How to conceive a boy or girl

When planning a pregnancy, many parents want to have a boy or, conversely, a girl. This requires knowing the exact day of ovulation. According to the theory of Dr. L. Shettles, the sex of the child is determined by the chromosomes of the sperm that fertilizes the egg.

If the sperm has a Y chromosome, then a boy will be born, and if it has an X chromosome, then a girl will be born. Male chromosomes are very active, but they die quickly, while female chromosomes live longer. Having sex the day before, at the time the egg is released and two days after ovulation, helps to conceive a boy. To give birth to a girl, you need to have sex 4 days before the release of the egg, and after its maturation, abstain from sexual relations for one week.

Important! The less often a couple has sex, the higher the likelihood of conceiving a girl. It is believed that infrequent sex leads to the formation of antibodies to the Y chromosomes. Sperm with X chromosomes have a greater chance of fertilizing an egg, which means there is a greater chance that a girl will be born.

How to determine the gender of your unborn child using a table

The sex of the unborn baby can be determined using a special Chinese table. The left column indicates the mother’s age, and the right column indicates the month in which conception is planned. Depending on how old the expectant mother is and when she plans to get pregnant, the sex of the unborn baby is determined.

To get pregnant, you need to accurately determine the date of egg maturation. Having sex during this period can guarantee conception. The sex of the unborn baby depends on the individual characteristics of the mother’s body and sperm activity.
