Ovulation calendar calculate gender online. What methods will help you find out the exact day of ovulation
female physiology It is designed in such a way that the ability to get pregnant is only 1-2 days per month. This most favorable period for conception in every woman is called ovulation. All internal genital organs are involved in this process, therefore, with different pathological disorders and failures menstrual cycle ovulation may be absent.
We recommend reading:The concept of ovulation
Ovulation includes a number of processes that occur in a woman's body in a certain sequence:
- the formation of a follicle in the ovary (this is repeated every month), in which the egg is surrounded by a special fluid;
- maturation of the follicle to the desired size by the middle of the menstrual cycle;
- opening of the follicle and exit from it to the outside, in abdominal cavity, and then into the lumen of the fallopian tube, the egg.
To be more precise, ovulation is exactly the moment when the egg, already ripe and ready for fertilization, leaves the follicle. Life cycle egg, when it is ready for fertilization - 24 hours. 
Ovulation occurs against the background of certain hormonal changes in a woman's body - 2 phases of the menstrual cycle:
- follicular - maturation of the follicle;
- luteal - the time from ovulation to the onset of the next menstruation.
Before ovulation, namely 24 hours before it, there is maximum level luteinizing hormone (LH) in the body. Its peak is provided by an increase in the concentration of another female sex hormone - estradiol to a certain limit. The latter is produced by the follicle that grows in the ovary. With an increase in the concentration of estradiol, the endometrium also grows. After ovulation occurs and the follicle opens, a corpus luteum forms in its place. It already begins to secrete progesterone, which prepares the endometrium for future pregnancy. At the peak of estradiol, basal temperature (measured in the rectum) decreases, and when progesterone secretion begins, it rises.
The ability to fertilize the egg remains only for 12-24 hours, and for sperm from 2 to 4 days. Given this fact, on the days of ovulation, the probability conception the maximum and equals 33%, in the following days after ovulation and 6 days before its onset, this probability is 0%, 3-4 days before - 15%, 2 days - 25%, 1 day - 31%.
Ovulation symptoms
Given that this process is hidden from the human eye, the signs of ovulation are subjective, that is, those that only the woman herself can observe and feel. Objective symptoms of ovulation are laboratory and instrumental techniques her research. The subjective definition of ovulation is based on the following changes in the body that allow a woman to determine it on her own:
- Vaginal discharge. In a few days, they become more than usual, and they have a lower viscosity, due to the influence of estrogen during this period. Discharge after ovulation sharply decreases in volume and takes the form of thick mucus.
- Pain during ovulation. A woman can feel a momentary sharp pain tingling character, which occurs in the lower abdomen on the right or left. This occurs precisely during ovulation, when the follicle bursts. This sign not typical for all women.
- sexual attraction. It may increase 1 or 2 days before ovulation.
- Bleeding. At the time of ovulation, very small (several milliliters) bleeding is possible, which does not affect the process of conception in any way.
All these symptoms of ovulation are observed on the 11-16th day of the cycle, depending on its length. note: how many days ovulation lasts can only be found out using instrumental diagnostic methods, but there are other methods that are less reliable, but more accessible.
How to determine ovulation: the most effective ways
The need to calculate ovulation appears in a woman when she, or vice versa, tries to avoid this in order to calculate “safe” days. Today, there are enough ways to determine this moment as accurately as possible. If this cannot be done independently at home, then there is enough laboratory and instrumental methods. In particular, today such methods of diagnostics are used ovulation:
- basal temperature;
- ovulation test;
- laboratory tests;
- ovulation calculator
- Ultrasound monitoring of the ovaries, endometrium;
- ovulation calendar;
- endometrial biopsy.
Basal temperature
It is measured exclusively in the morning after sleep. Without getting out of bed, insert the thermometer into the rectum for 5 minutes. Data is recorded daily and plotted based on it. basal body temperature. 
In the days before ovulation, there is a decrease in basal temperature, and immediately at the time of its onset sharp rise by 0.5 - 0.6 divisions of the thermometer.
Ovulation test
It is designed for home use. To determine the exact day of ovulation, the test will have to be repeated more than once. It has the form of a test strip, which can be purchased at every pharmacy. Such a test responds to an increase in luteinizing hormone in the urine. The peak of its concentration during a normal menstrual cycle is observed 24 hours before the onset of ovulation itself. Such a test should be performed 2 times a day, daily, starting a few days before the expected date. 2 strips on an ovulation test indicate that on this moment the body of a woman is as ready as possible for conception. One line indicates that the test is workable, and the second reflects the level of luteinizing hormone. 
note: if the second strip on the ovulation test is paler than the control (repeated during each cycle), then this may be a symptom of the absence
ovulation
due to the presence of pathology in the body (often hormonal). It should also be taken into account that normally 1-3 cycles per year can be anovulatory, and the older the woman, the more they become and this is not a pathology. If ovulation does not occur regularly, then this requires medical intervention, a full examination and treatment.
The ovulation test is not suitable for women who have the following conditions:
- not regular cycle;
- diseases of the endocrine system;
- chronic stress, against which LH levels are often elevated, which can give a false positive test;
- polycystic ovary syndrome.
Laboratory tests
Gynecologists in their work use some functional tests in order to calculate the day of ovulation. They are inexpensive and affordable, but require a woman to visit the gynecologist for several days in a row, which can be problematic. These tests are based on the study of the characteristics of secretions fromvagina.
- fern symptom. The doctor takes mucus from the cervix and places it on a glass slide. Due to a significant increase in potassium and sodium salts in it before ovulation, after the smear dries, the mucus crystallizes, forming a pattern in the form of a fern leaf.
- Extensibility cervical mucus . A couple of days before ovulation, the discharge has White color and stretch about 1 cm, on the day of ovulation they take on the appearance of egg white and stretch for several centimeters. After ovulation, they become sticky, thick and there are very few of them.
- Symptom "pupil". During the examination, the doctor notes the ajar cervical canal.
The reliability of such tests in reality does not exceed 50%.
Ovulation calculator
Today there is a special program that helps to determine the least and most auspicious days for conception - ovulation calculator. With it, you can calculate ovulation for each woman individually, provided that she has a physiologically normal menstrual cycle (28 days). In order to use the calculator, you must enter 2 numbers: the date of the last menstruation (its first day) and the duration of the cycle itself. The program will give you the results. The reliability of this method of determining ovulation is relative.
ovarian ultrasound
This method is considered the most informative and allows you to get the following information:
- the state of the endometrium;
- growth dominant follicle;
- detection corpus luteum, which is formed on the spot former follicle, and parallel changes in the structure of the endometrium.
Ultrasound monitoring allows the doctor to accurately record the moment when the follicle enlarges and ruptures, that is, the very moment of ovulation. At the same time, the gynecologist always advises to simultaneously keep a graph of basal temperature and take functional tests. For a cycle, 2 ultrasounds are enough to determine on which day ovulation occurs.
The first ultrasound is carried out in time as close as possible to the expected day of ovulation, where the presence and size of the dominant follicle are determined. The second study is carried out on the basis of the approximate day of ovulation based on the growth rate of the follicle. On average, it grows by 2 mm per day and reaches a maximum of 20-24 mm. In parallel appointed laboratory tests to progesterone and estradiol levels. Ultrasound is also often used as a diagnostic after ovulation stimulation to determine it. the exact date offensive.
Ovulation calendar
This is an individual scheme. every woman's menstrual cycle. It marks the date of the beginning, end of menstruation and ovulation. Also, in such a calendar, the sexual acts that have occurred are recorded. Drawing up such a calendar will be useful, not only for those who want to conceive a child, but also for those who do not yet have motherhood in their plans (calculate " safe days"). This calendar is similar to the ovulation calculator, but it is compiled manually. With its help, a woman can independently learn, over several cycles, to determine the moment of ovulation, taking into account the characteristics of her body. It is necessary to fix the data in the calendar for at least 6 months before calculating ovulation.
note: the individual fertile period is calculated in this way: 11 is subtracted from the longest cycle, and 18 is subtracted from the short one. For example, 28-11 \u003d 17 is the last day of a woman’s fertility (where 28 is the longest cycle), fertility day, where 26 is the most short cycle. As a result, from the 8th to the 17th day of the cycle is the most favorable period for conception, since it is in this interval that ovulation occurs. Most women have a regular cycle of 28 days, in which ovulation occurs on the 14-15th day. An example of an ovulation calendar with a cycle duration of 32 days: 
Biopsy of the endometrium
This is instrumental method ovulation diagnosis. It is rarely used, only if other technologies are uninformative. During ovulation, namely in the middle of the luteal phase, the endometrium is transformed, that is, its secretory transformation occurs, and its presence is a sign of the maturation of the follicle.
Ovulation and conception
The menstrual cycle of a woman consists of 3 periods regarding the likelihood of conception:
Fertilization, released from the follicle, the egg is possible only during ovulation. For this, the woman's body is specially prepared:
- increased secretion of cervical mucus to facilitate the passage of spermatozoa;
Ovulation is the phase of the menstrual cycle during which the mature egg is released from the follicle and enters the fallopian tubes for fertilization by sperm.
Only a day is allotted for conception by nature, but it is rather difficult to guess exactly on which day of the cycle ovulation will occur, because there are many factors that affect this process: hormonal imbalance, diets, diseases, medications taken, etc.
To date, there are many methods to determine and calculate the correct "day X", i.e. ovulation. With their help, you can not only find out a favorable day for conception, but also prevent the onset of an unwanted pregnancy.
Methods for calculating the day of ovulation
calendar method
Everyone has long known that a woman's menstrual cycle has a clear cycle and regularity. Certainly, we are talking about healthy and normal periodicity without obvious deviations. If this is your case, then ovulation can be calculated literally in your head, knowing the exact number of days of your cycle. Due to individual characteristics, each woman has her own cycle length - one has 28 days, the other has 32. In both cases, the values fit into the norm, as they are in the range of 21–35 days. Experts have found that ovulation occurs exactly 14 days before the onset of menstruation.
If your menstrual cycle is clear as a clock, then for correct definition"Day X" you need to solve a small arithmetic operation:
M - 14 days = O
Where M- the day of the onset of the next menstruation, and O is the day of ovulation.
For example, if the date of the next menstruation falls on June 20, then 14 days must be subtracted from this date. As a result, we get June 6th. This date is the day of the expected ovulation.
Online calculators are built according to the same computational scheme as the above formula. To calculate ovulation, you only need to enter certain data about the menstrual cycle, and he will be able to calculate everything else by himself.
According to basal temperature
Basal body temperature (BT) is the lowest body temperature that occurs after a long night's sleep. It is necessary to measure it immediately after waking up, without getting out of bed, by the rectal method. With the help of BT, you can track the process of changing the temperature of the female body, depending on the phases of the cycle. During follicular phase(first) temperature keeps low values ranging from 36.3–36.8˚С. The day before ovulation, the temperature rises, and on “day X” it reaches 37.1–37.3 ° C and stays in this position throughout the entire luteal phase (second) until the onset of menstruation. With the onset of a new cycle, everything repeats in a circle.
In order for the BT indicators to be reliable, it is necessary to follow all the measurement rules and take into account the state of the body when calculating. Any disease, fatigue, medication, alcohol consumption can affect the indicators of the BT schedule.
According to ultrasound
An ultrasound scan can most accurately calculate the release of an egg from a dominant follicle. With regular monthly cycle Ultrasound is performed 2-3 days before the expected date of ovulation. At irregular cycle- for 4-5 days every 2 days.
According to the phenomenon of saliva crystallization
The hormonal balance of a woman is characterized by a certain ratio of hormones in different periods menstrual cycle. In its first part, estrogen predominates, which decreases with the advent of ovulation. The second part is characterized by the predominance of another sex hormone - progesterone. Saliva in its composition and nature of processes is similar to uterine mucus. During the period of ovulation in saliva, the level of salt content rises, which is easily monitored under a microscope. It is these salts that will help you determine and calculate the exact date. To date, special devices-microscopes are actively sold, according to appearance similar to lipstick. Just a minute and you yourself can find out your readiness for conception by examining the patterns of saliva composition in the eyepiece of a similar microscope test.
Hormonal fluctuation of sex hormones is accompanied by characteristic changes saliva crystallization. Approximately a week before ovulation, saliva begins to form fuzzy clusters, in which signs of the image of a fern leaf or spruce twig are noted. With the advent of ovulation, this picture acquires the intensity of crystalline clusters. Three days later, the image begins to lose clarity again.
This method gives a 99% guarantee, but only under certain conditions: no inflammatory processes mouth, no smoking, no food 2 hours before the test. For greater reliability of the result, testing is best done immediately after sleep, even before brushing your teeth.
In addition, using a microscope, you can track the overall hormonal state of the body. Intense or blurry accumulations of crystals throughout the cycle, the monotony of the pattern without visible changes at the right time, shifting the timing of ovulation and other suspicious processes - the need to see a doctor.
With the help of a test
This is perhaps the most popular way to determine ovulation today. In addition, there are no obstacles to acquiring the test - there are plenty of them in every pharmacy. The principle of operation is similar to a pregnancy test, only you need not to determine ovulation chorionic gonadotropin contained in the urine, and luteinizing hormone. All the same two stripes positive result, should also appear on an ovulation test, one strip is a negative result.
The test cannot give a 100% guarantee, since many factors can influence the hormonal “environment”. In addition, two immature follicles can simultaneously give a positive result.
By well-being and discharge
Some women do not need to seek help at all to calculate the day of ovulation. helper methods. Their nature and idiosyncrasy they themselves will show signs of the onset of "Day X". During ovulation, women may experience short-term pulling pains in the lower abdomen, swelling of the mammary glands, increased libido and the appearance of specific vaginal discharge. Discharge during the ovulatory period becomes abundant, transparent and viscous, reminiscent of the consistency egg white. In the break test, a string of cervical mucus will be stretched between two fingers.
Of course, the unusual behavior of the organism or nagging pain may indicate a health disorder, but women in whom such phenomena occur from month to month are able to correctly determine where the ovulatory signs are and where the general condition is disturbed.
As we can see, our body itself answers all questions, it is only important for us to learn how to correctly recognize its signals and signs. How to calculate ovulation? The main thing is to be able to calculate your menstrual cycle, and progress will do the rest.
Calculation of the day of ovulation, the menstrual cycle and favorable days for conception and pregnancy.
With this calendar you can calculate the days ovulation, i.e. when the probability of pregnancy is maximum and determine the most favorable days for conceiving a child (boy or girl) without pharmacy ovulation tests for determining days of ovulation. The conception calendar helps women planning pregnancy to calculate the days of ovulation and create a personal conception calendar. You can chart your female menstrual cycle months in advance! You'll get menstrual calendar for 3 months, which will indicate: ovulation day, fertile days, days for conception of a boy and a girl. Do not confuse the duration of menstruation (monthly) and the duration of the menstrual cycle! The ovulation calendar is interactive: hover your mouse over a day in the calendar and read more information.
Asking the question of pregnancy, a woman is looking for opportunities to speed up the process as much as possible. To do this, you need to be able to identify the moment when female cage"ready" using different methods, and also know the rules to calculate ovulation, including online.
What causes ovulation - processes
- A follicle grows in the ovary. This is a special bubble in which the cell is born.
- Reaching optimal size the follicle ruptures.
- The vacated cell begins to move along the female paths.
- If in this segment she meets a sperm cell, contact will occur, leading to conception.
- After that, the cell will approach the uterus and be fixed. This is where the embryo will develop.
- In the place of separation from the ovary, the corpus luteum will grow. It produces a hormone that promotes pregnancy.
The third stage is ovulation. Its length depends on the vital activity of the cell. Usually, this is a day, less often - 36-48 hours. That's why you need to know how to calculate ovulation in order to get pregnant. Indeed, due to the brevity of the process, it is easy to miss it.
If the meeting does not happen, the cell will die in a day. The corpus luteum will still form, since this procedure is necessary for the normal completion of the process. At the appointed time, menstruation will come and everything will repeat itself cyclically.
Knowing the duration of each stage, how to calculate ovulation and prescribe a personal calendar, it will not be difficult at all.
Cell maturation time varies for everyone. Ideally, it is 14 days, but in practice it is between 11-16 days. Due to such an error, this parameter cannot participate in the calculation. The second stage, associated with the development of the corpus luteum and the preparation of the ovaries for a new cycle, is static in all women - 14 days. This figure does not change at any distance between menstruation.
How to calculate ovulation mathematically
Consider an example of how to calculate ovulation in order to get pregnant and prescribe a calendar for productive sexual intercourse. First of all, you need to calculate the length of your cycle - the distance between the first days blood secretions. The ideal number is 28 days.
You need to subtract 14 from your value. In our case, it also turns out 14 days. That is why it is considered the norm when both periods are equivalent. Now you need to count from the first (inclusive) day of menstruation 14. It's easier to do this on the calendar. Having put a mark on the 14th day, you should paint over two more dates for yourself: the next and the previous one. This is necessary, since the cell lives for some time, and it can be "captured" at any time. By activating the process of delivering male spermatozoa, you can expect the result with great confidence.
By the way, knowing the characteristics of the vital activity of spermatozoa and some scientific points, you can calculate ovulation for the conception of a newborn of a specific gender. Here are the facts:
- Gender does not depend on the female cell.
- Male cells with a Y chromosome are very active. They reach their destination faster. In the absence of a finished cell, they will soon die. Duration of operation - up to a day.
- Cells with the X chromosome are slow. They will not keep up with fast Y anyway. But they live for a long time - up to 3 days. That is, provided that Y all died, and the female cell appeared later, X will easily reach it, having no competitors.
Now it’s clear how to calculate the day of ovulation for conceiving a boy. It is necessary to identify the specific moment of the appearance of the cell and perform sexual intercourse only after that. Y-cells will quickly reach it and fertilize it, and the slow X-cells will not keep up. If there is a desire to get a girl, you should do something completely different - appoint an act 2 days before the release of the cell. In this case, the following processes will occur:
- Y cells will stop functioning and die after 24 hours.
- After their disappearance, after another 24 hours, the cage will come out.
- At the time of its passage through fallopian tube there will be no one except X-type cells. Therefore, it is they who will carry out fertilization and determine the sex of the baby.
The main thing is not to repeat acts later. Otherwise, Y can "survive" and prevent the achievement of the desired effect.
Online ovulation calculator
Today, many offer to interactively calculate ovulation, there is an online calculator on many sites. For example, you can use it by clicking on the link.
To use it, you need to fill in the indicated fields: the date of the last menstruation, the length of your cycle, total days with characteristic bleeding and indicate for which period to paint the calendar. The second option is offered for women who do not control their rhythms. Therefore, it is enough to enter two parameters: the days of menstruation for the last months.
You can not just calculate the day of ovulation, the online calendar makes it possible to predict even the sex of the newborn. The formulas involve the generally accepted principles that we discussed above. As a result, the woman receives a ready-made calendar for as many months as she requests, which states:
- days of bleeding;
- the exact moment of ovulation (the maximum probability of getting a son);
- days when the cell is active and intercourse will result in a boy;
- days when the highest probability of conceiving a daughter (provided that there is no sexual activity at the time and after ovulation).
Calculating ovulation days online is very simple. This provides several benefits. In particular, there is no need to constantly monitor the cycle and calculate the days. There are ready-made calendars for six months or more. Based on them, it is easy to detect a failure. For example, if menstruation did not come on time or the rhythm changed. In such a situation, you will need to re-request new calendar subject to change.
Before you count the days of ovulation in order to get pregnant and draw up a calendar for the desired period, you should understand the error and shortcomings. Most of them are about gender. It is not worth focusing on all the shaded days. Still, it is better to adhere to the rules established by experts. Mathematical calculation does not take into account the characteristics of the body. It's no secret that there is a certain percentage of girls suffering from irregular cycles. Their number of days between periods varies monthly. For such a situation, it is almost impossible to calculate the days of ovulation on a calculator. The data received will be irrelevant.
To get any reliable effect, it is better to enter data on its smallest value. But at the same time, the forecast of sex is completely excluded. It is worth trying other methods that will be more truthful for such girls.
Characteristic signs of ovulation
- Abdominal pain . Observed from the side of the ovary, which is currently producing a cell. As we remember, it comes out under the condition of rupture of the follicle. Naturally, this is accompanied by pain, albeit insignificant. Some may not notice it. But if you listen to yourself, you will not miss the moment. Having learned the exact day of release, you can begin to conceive.
- Soreness of the chest. The mammary glands swell somewhat, increase, which causes some unpleasant pain when rubbing clothes, for example. The sign of the restructuring of the body with a possible future pregnancy and breastfeeding is explained.
- Libido. Since the cell has left, the body is preparing for the birth of life, therefore it sends impulses to the brain, speaking of the need to be fertilized.
Do not forget about the possibility of how to calculate the day of ovulation by female secretions. It is known that in the first phase, girls do not notice any mucus. It has a fairly dense structure and blocks access to the uterus. This keeps it from being exposed to microbes and prevents sperm from entering during a period when they are not needed.
As the follicle grows, the secret gradually liquefies. By the time the cell arrives, the mucus already acquires its own special structure:
- transparent;
- thick, viscous;
- a large number of.
Safety net - ovulation tests
Having chosen your own way, how to calculate the day of ovulation for conceiving a child, do not forget about some additional methods. They can be used to confirm mathematical formulas and play it safe, if knowing a specific day is very important. First of all, this different kinds tests:
- Strip tests. Cheaper and affordable option. Having lowered it into the urine, it is necessary to wait for the change in shade on the strip and compare it with the control. Reacts to the amount of the hormone. The error is caused by different content of normal LH.
- Inkjet. A similar option, they differ in the method - it is necessary to substitute it under the stream, and not collect urine.
- Electronic. The strips are inserted into the device, used according to one of the above methods. The advantage is that there is no need to match shades. The test result will be shown on the screen.
To use any test, you need to know how to calculate the ovulation cycle and at what point to start the analysis. How to find out the first, we have already considered. And the formula for prescribing the first test is generally accepted: subtract 17 from the first indicator. It will take several days to conduct it until the result pleases.
If there is a problem with detecting ovulation, you can afford a more expensive device that will help you reliably determine the moment by saliva. It is reusable and mostly looks like a microscope.
Shouldn't be discounted basal chart or ultrasound. They will be more interested in ladies with non-rhythmic cycles, because their reliability is many times higher. Now you can be sure that you know everything about how to calculate ovulation.
