How to determine ovulation online. Ovulation calculator

Ovulation is the so-called X day, which is eagerly awaited by many couples who want to conceive a baby as soon as possible. This day can be calculated and determined independently or with the help of specialists.

You can get pregnant only on certain days of the cycle, about seven of them in one month. For most young girls this is real news! It turns out that not everything is as simple as it seemed during my student years.

Every woman should have an idea of ​​what ovulation is. For some, this is an opportunity to get pregnant quickly, for others, on the contrary, to avoid unwanted motherhood. In the second case, you should not rely only on calculations; you should always use additional methods of contraception.

During ovulation, an egg (and in rare cases more than one) is released from an ovarian follicle in anticipation of a sperm for fertilization. If conception does not occur, the egg dies and the next period begins. And so on from month to month. Critical days replace ovulation and vice versa, this happens from the moment of puberty until the onset of menopause.

Conception occurs if, during ovulation (plus or minus a few days), sexual intercourse occurs and the most active sperm reaches its goal. Why are several days favorable for fertilization, and not one, the day of ovulation itself? The fact is that sperm can live in the female body for several days, traveling through the fallopian tubes. Therefore, theoretically, you can get pregnant on the second or third day after intercourse. For example, you are driving, and you don’t know that an important event has happened at that very second! By the way, knowing this principle, you can try to guess the gender of the child.

Whether you get a boy or a girl depends entirely on your man. The fact is that a woman always has an X chromosome, but a man either has an X or a Y. With a combination of XX, the result is a girl, and with XY, a boy. Each sperm contains both chromosomes, but one is initially more pronounced than the other. In simple words, we can formulate this way: each sperm carries a feminine or masculine origin.

“Male” sperm reach their goal faster, and “female” sperm, in turn, live much longer. This means that in order to become pregnant with a girl, sexual intercourse is necessary 2-3 days before ovulation. During this time, the “male” sperm will die, giving way to the “female” ones. But for a boy, it’s better to wait just until day X. The boys will shoot ahead, overtaking the girls and trying to reach the goal as quickly as possible. It is clear that there is no 100% guarantee, but still the chances of getting the desired gender increase significantly if you adhere to these rules.

Whether you want a boy, a girl, or just get pregnant and give birth to a healthy baby, it all comes down to one thing - you need to determine the favorable time for conception. This can be done both at home and with the help of specialists. In addition, the body itself can tell you that it is ready for fertilization.

Signs of ovulation

It will be news to some, but ovulation is often accompanied by certain signs, although in many women it is asymptomatic. Some of them you can notice on your own:

1. Change in the nature of discharge. They become somewhat more plentiful, with a consistency reminiscent of a raw egg.
2. Increased sexual desire. This is how nature cleverly planned for the continuation of the human race.
3. Sensitivity in the chest area, even pain is possible. This occurs due to a hormonal surge during ovulation.
4. During ovulation, the stomach pulls on the right or left. This is explained by the release of the egg from the right or left ovary.
5. Increase in basal temperature.
6. Changes in the cervix. It softens a little and opens slightly, hence the change in the nature of the discharge.
7. A surge of luteinizing hormone (LH). Due to this, mature eggs are released.

A woman can notice the first four signs on her own, but the last three only with the help of specialists or special devices.

In rare cases, women experience anovulation - the absence of ovulation as such, a disruption of the menstrual cycle. If a couple cannot conceive a child for a long time, the first step is an ultrasound to track the progress of ovulation.

How to determine ovulation

If a woman does not have pain during ovulation, she may not even know that she is now ready to conceive. Discharge during ovulation also does not necessarily have to be unique for everyone and in each cycle. And a change in sexual desire is quite a subjective sign. Therefore, there are a number of ways to determine ovulation at home or with the help of doctors.

Ovulation calendar

So, we take the most ordinary calendar, in which the start and end dates of critical days are recorded for several months, and so on for at least six months.

First, based on these data, you need to calculate the length of the cycle, that is, the number of days between the first days of menstruation in two months in a row. We subtract 14 from the resulting indicator and get the day of ovulation. For example, if the cycle is consistently 28 days, then ovulation will occur on the 14th day of the cycle. From here it becomes clear why calculating the day of ovulation is possible only for girls with a regular cycle. If it constantly jumps, and in one month it is 27 days, in another 35, then it is difficult to predict how many days it will have in the next month.

Ovulation tests

Nowadays there are not only pregnancy tests on sale, but also ovulation tests. Unlike the former, they respond to an increase in LH, and not hCG.

Tests should begin to be done a few days before expected ovulation, since the hormone begins to rise 1-2 days before the egg leaves the ovary.

Unlike a pregnancy test, ovulation tests have some nuances that should be taken into account to ensure the results are as accurate as possible:

1. Morning urine is not suitable! The optimal interval for collecting urine is from 10-00 to 20-00.
2. You do not need to drink any liquids for 4 hours before the test.
3. You should refrain from going to the toilet for 2 hours.
4. Read the instructions carefully! Each type of test has its own nuances. Somewhere you need to collect urine, somewhere on the contrary, it’s enough to place it under the stream.

There are more expensive tests that can detect ovulation using saliva rather than urine.

Basal temperature measurement

It is necessary to measure the temperature in the rectum the next morning immediately after sleep. On the day of ovulation it should increase. Based on the data, you can even create your own ovulation calendar, and if you keep it for several months, you can try to make a forecast for the future. However, again, it will only be accurate for girls with a constant and regular cycle.

It should be borne in mind that the temperature may jump slightly in case of illness, restless and short sleep (less than 6 hours), or taking alcoholic beverages or medications the day before. When measuring temperature, this feature of the body must be taken into account!

After the critical days and before ovulation, the temperature has slight fluctuations - approximately 36.6 - 36.9. But immediately after ovulation, its values ​​​​exceed the reading of 37 degrees.

In order to obtain the most accurate measurement results, it is necessary to measure the temperature with one thermometer and under equal conditions - at the same time after a quiet, long sleep.

Medical diagnosis

Usually, doctors can determine ovulation of the ovary during examination in the gynecological chair. As already mentioned, on this day the cervix visually changes, softening and opening slightly.

To confirm ovulation, a woman may be sent for an ultrasound. With the help of modern equipment, diagnosticians are able to determine whether ovulation has occurred, and if so, at what stage it is.

Typically, medical diagnosis is carried out after unsuccessful attempts to get pregnant for a long time. You should start coming for an ultrasound on the 10th day after your period. In order for specialists to track the growth of the dominant follicle in the ovary, they will have to come several times until the diameter of the follicle is about 20 cm. Then it will rupture and another egg will be released, ready for fertilization. During this period, you can see on the screen the corpus luteum, located in the ovary without a follicle.

Some nuances you should know

First of all, this will be of interest to women who calculate ovulation for contraception purposes. As already mentioned, this method is very dubious. There are millions of examples of unwanted pregnancies caused by blind numbers. Therefore, in order not to think about the moral side of abortion, which is officially permitted in our country, it is better to play it safe and always use additional methods of contraception. Some people have been trying to conceive a baby for years, while others succeed unexpectedly and on the first try. You should not play this roulette if you are not ready to become parents.

There are several other factors that work against the calendar method. It turns out, paradoxical as it may sound, if a woman does not have regular sex life, her chances of pregnancy are much higher! At the very first sexual intercourse, unscheduled ovulation may occur - the body will not want to miss such a rare opportunity. After all, nature created a woman to procreate.

Having sex during menstruation is considered safe. Indeed, during this period the environment is quite unfavorable for sperm and they die earlier than usual. However, if a woman has an irregular ovulation cycle, then there is still a chance of getting pregnant. If sexual intercourse occurred in the last days of menstruation, and ovulation occurred earlier than usual, there is a chance that sperm will wait for the egg in the fallopian tubes.

Children are our joy; we have them for the rest of our long and happy lives. Therefore, the issue of pregnancy should be approached very responsibly, planning it in advance and creating appropriate conditions for the unborn baby. Remember that unloved and unwanted children always feel their attitude towards them, growing up angry and distrustful of the world around them.

Let's summarize

So, ovulation is a process in a woman’s body that signals that she is ready to conceive. It should be calculated and determined by other methods for couples who want to have a baby in the near future. It is useless to do this as contraception; it is better not to skimp and use other methods.

Video " Symptoms of ovulation - 8 main signs"

Ovulation is the main factor determining a woman's ability to conceive. That is why a woman who wants to get pregnant must know the day the egg is released from the ovary (the day of ovulation). Determining the exact date can be done in several ways:

1. Use the calendar method.
2. Observe your body and, based on its changes, determine the most favorable date for conception.
3. Conduct a special test.
4. Conduct an ultrasound examination.
5. Measure your basal temperature.

Some methods require a long period of preparation (up to six months in the case of the calendar method and measuring basal temperature). But first you need to understand what ovulation is and how its date affects a woman’s fertility.

About the ovulation process

A woman's menstrual cycle is an indicator of her body's ability to conceive. First, the egg matures, then, ready for fertilization, it leaves the ovary (ovulation), then pregnancy can occur only within 24 hours. If the sperm is not encountered on the way to the egg, then conception does not occur and after some time menstruation occurs, starting a new ovulatory cycle.

The sperm retains the ability to fertilize for several days (rarely up to a week). This means that for successful fertilization, it is necessary that the man’s seminal fluid enters the woman’s body either a few days before ovulation or immediately after its onset. On other days, sexual intercourse is useless from the point of view of pregnancy. Therefore, knowing the exact date of ovulation is so necessary for couples planning to conceive.

How to determine the day of ovulation most accurately?

Calendar method

Most often, the time of ovulation occurs in the middle of the cycle; the calendar method is based on this. In women whose cycle is about 28 days, the release of the egg is observed on days 14-16. To more accurately determine a specific date, it is necessary to maintain an accurate schedule for the onset of menstrual bleeding for six months. In this schedule (calendar) it is necessary to mark the day when menstruation begins and the day it ends. Next, you need to determine the longest cycle and the shortest. To determine the earliest date for the release of an egg, it is necessary to subtract 18 days from the duration of the shortest cycle; to determine the latest date for the release of an egg, subtract 11 days from the duration of the longest cycle.

Example: the shortest menstrual cycle is 25 days (25-18=7 – on the seventh day after the start of menstruation, the release of the egg may begin); the longest menstrual cycle is 31 days (31-11=20 - the twentieth day is the latest date of ovulation). It turns out that favorable days for conception begin on the 7th day and end on the 20th. If the cycle is more constant, then the date is calculated more accurately.

Determining ovulation by calendar is not accurate, but indicates the period of time in which it theoretically occurs. There may also be individual characteristics of a woman in which the release of an egg may occur during menstruation, or immediately before monthly bleeding. Disruptions in the menstrual cycle are also possible due to various reasons: taking medications, physical activity, overwork, stress, nutrition and others.

Physiological signs

If a woman carefully monitors her body during the menstrual cycle, then the date of ovulation can be determined even without special devices and complex calculations. There are several signs that indicate the release of an egg from the ovary.

1. Change in vaginal discharge. More often they become abundant, acquire a yellowish tint, and look like mucus. Often the rupture of the follicle is accompanied by the release of a small amount of blood, which can turn the discharge pink or brown.
2. Pain on one side of the abdomen. It can feel like pulling or cutting.
3. Increased desire for intimacy. As a rule, a woman’s libido is activated on favorable days for conception under the influence of hormones. Many women who have irregular sex life can almost accurately determine the date of release of the egg by this sign.
4. Changes in the cervix. During ovulation, the cervix opens slightly, rises slightly and softens. To increase the reliability of the results, it is necessary to conduct a daily examination of the cervix, observing the rules of hygiene. It may take more than one round of regular self-examinations to notice the differences.
5. Breast changes. Hormonal activity of the body during the period of ovulation can provoke engorgement of the mammary glands and their soreness. Often such phenomena are observed immediately before or immediately after the release of the egg.
6. Crystallization of saliva. Determining the day of ovulation using this method requires a microscope and some skills. Scientists have noted that a day or two before the release of the egg, under a microscope, a woman’s saliva resembles frost.
7. Changes in the perception of smells and tastes. On the eve of ovulation, your sense of smell or taste may become more intense. Some representatives give up perfume on such days and note an increased sensitivity to odors that they practically did not notice before (the smell of paper, office furniture, household appliances).
8. Increased flatulence and abdominal swelling. Often a small focus of inflammation appears on the abdomen on the side of the ovary, which has become active in the observed cycle.

Structure of saliva under a microscope

Methods for determining ovulation by physiological signs are not accurate; they may appear shortly before the release of the egg, or not appear at all.

Pharmacy test

You can purchase tests at the pharmacy to determine the exact date of ovulation. They are based on determining hormone levels. The fact is that immediately before the release of the egg, the production of luteinizing hormone (LH) is activated, which is what the test strip detects. Before using the test to determine ovulation, you must read the instructions. LH is constantly present in the urine on any day of the menstrual cycle, so the second strip always appears, it can be a rich color or only slightly pink. Only in the first case is there a high probability of ovulation after a day or a day and a half.

An ovulation test must be taken at the same time every day. It is advisable not to urinate for about 3-4 hours before the procedure. Drinking plenty of fluids can reduce the concentration of LH in the urine.

There may be some errors in this method, since it determines the change in hormone levels after which ovulation occurs, and when exactly this happens is the individual characteristics of each organism. The level of the hormone may increase in certain diseases of the endocrine system, renal failure, postmenopause, and ovarian wasting syndrome. A false positive test result is possible when pregnancy occurs or is stimulated by medication. Nutrition, in particular phytohormones, can also affect the result.

Dynamics from 10 to 13 days of MC

Ultrasonography

Ultrasound to determine ovulation is the most accurate method known. During this examination, the doctor sees the egg and its location in the reproductive organs. First, it is necessary to carry out the procedure on the 8-10th day of the menstrual cycle with a duration of 28 days - this will determine the degree of maturation of the egg and predict the date of ovulation. Further research is carried out on the individual characteristics of folliculogenesis (ovum development). In total, up to 3-4 ultrasounds may be required.

How to determine the date of the first ultrasound with an irregular cycle?

If a woman’s cycle lasts more or less than 28 days, then other methods (the calendar method in particular) are used to determine the expected timing of the release of the egg. The first ultrasound examination is carried out 4-5 days before the expected date of ovulation.

Basal temperature measurement

It has long been noted that a woman’s body temperature changes depending on the time of the menstrual cycle. Determining ovulation by basal temperature requires regular measurements and compliance with strict conditions:

1. The temperature is measured immediately after waking up. You cannot walk, sit down, talk, shake off the thermometer, etc. It is necessary to prepare in the evening (shake off the thermometer and place it near the bed).
2. Before the measurement, you need to sleep continuously for about 5 hours.
3. The procedure is carried out between 6 and 7 am at the same time.
4. The temperature is taken rectally (in the rectum), vaginally, or orally (in the mouth) over 5 to 10 minutes. You need to choose one method and use only it.
5. They use one measuring device; if it is necessary to change it, then the day of the change should be noted.
6. Temperatures measured during illness and after drinking alcohol are excluded from the analysis.
7. Changes in the situation must be noted in the schedule (business trip, relocation), this may affect the readings.
8. Temperature measured when taking contraceptive drugs orally is not informative.
9. At least 3 months of regular measurements are taken for analysis.

All measurements are recorded on the graph. The cycle must be divided into two phases. At first, there is a slight fluctuation in temperature from 36.3-36.8 degrees, then a short-term decrease and a sharp jump above 37 units (ovulation). Further, the temperature remains above 37 units until menstruation, and then decreases.

Normal two-phase schedule

Deviations from the standard basal temperature schedule (sharp fluctuations, or lack of separation into two periods) may indicate serious disorders of folliculogenesis and. Also, such a graph may indicate a woman’s dishonesty and disregard for the rules for measuring temperature.

We increase the likelihood of getting pregnant

If you and your loved one decide to have a child, but you do not have regular sexual relations, an ovulation and conception calendar will help you.

This is such a convenient thing that will show on what day the probability of starting a pregnancy is higher. But before we use it, let's figure out what it is and how it works.

The calculator performs simple calculations for the next few months, showing you when the next ovulation will occur, unless unforeseen events, illnesses or any deviations occur.

This information is necessary for every woman hoping for an early pregnancy. And the calculator can provide it. Receiving the beginning and length of the menstrual cycle instead of input data, he describes the entire period step by step.

What is ovulation?

First, we need to understand what ovulation is and how it affects pregnancy.

Ovulation is a special day in the menstrual cycle when there is a high probability that conception will be successful. How does a child appear? The egg needs to be fertilized.

About a week after the end of menstruation, a new egg has already matured in the woman’s body, ready to become a baby. If you fertilize it on time, you will get a fruit. If you do not fertilize, in another week and a half a new period will begin.

But that special period, lasting no more than two days, shows when the uterus is ready to accept the embryo and the egg is ready to be fertilized. Unfortunately, the lifespan of an egg is short - from 12 to 36 hours.

Therefore, it is very important to know exactly when ovulation occurs so as not to miss the right time.

For men, such a calendar is not needed - sperm live long and are constantly renewed. So your partner is ready to conceive a child any day if he wants it.

How to calculate the moment?

You don't have to do the calculations yourself. For this, there are many online programs that allow you to quickly and free calculate your ovulation date.

This calculator will save you time and easily tell you when you should become more active in your sex life in order to start pregnancy. You will receive a convenient calendar on which everything will be marked simply and clearly.

To calculate the date of ovulation, you need to know only two things: the days of the beginning of the last and penultimate menstruation. If you have an irregular cycle, it is better to take more dates. Look at the period between them and get the cycle length.

If the numbers are different for different months, then we take the latter. These calculation conditions are easy to remember: it is rare that a woman does not remember when her period began.

When you enter the day of your last menstruation and the length of your cycle into the online calculator, the program will be able to calculate your entire period. The probable day of your next period will be marked in red.

Light green – the middle of the luteal phase. This is the time when the egg appears and develops. These days are the average probability of starting a pregnancy.

Green color indicates the day of ovulation, the highest probability of conceiving a baby. But this does not mean that the calculator is 100% correct and you need to try hard only at this time.

Sometimes the egg is ready and alive a little earlier or a little later. Therefore, the approximate time is the day marked in green, plus or minus another day.

This online calendar allows you to know the most successful days several months in advance. You can print it out and put it in your desk so you can refer to the dates. In addition, the calendar will remind you of your upcoming period.

Other signs of ovulation

The middle of the cycle is far from the only landmark of a good time for pregnancy. The days when the egg is most ready for fertilization will be slightly different from the rest.

For example, estrogens affect a woman’s body even during the development of the egg, even before it is fertilized, before pregnancy begins. And these changes can be tracked:

• A slightly viscous discharge appears from the genitals. This does not last long, a couple of days at most.
• On the day of ovulation, a woman's temperature drops slightly. It may not be very noticeable, but if you measure it every day, small deviations will help calculate the time of ovulation.
• A slight aching pain, as if you had slightly pulled your abdominal muscles. It does not always appear, but is often a consequence of ongoing ovulation.
• Increased sexual excitability.

The online calculator will provide you with a calendar that allows you to narrow down the period of greatest activity.

But it has other uses too. Such a calendar may not be the most accurate, but it is still a method of contraception.

But remember: there is always the possibility of error, for example with an irregular cycle. The calendar cannot be considered an ideal remedy for pregnancy.

Many believe that conception relative to ovulation greatly influences the sex of the child. If the child was conceived before ovulation, most likely it will be a girl, and if after, it will most likely be a boy. Believe it or not - it's up to you. However, knowing your cycle will help you a lot.

Many women are familiar with the concept of ovulation. For those who don’t know, ovulation is a relatively short period of time during which the likelihood of fertilization reaches its peak. Calculating this interval is extremely important for married couples trying to have a child. But even the most accurate calculations are not a 100% guarantee of conception.

So, ovulation is the period between the phases of the monthly cycle, lasting about two days. What is so special about this process that regularly occurs in the female body?

During ovulation, the egg (mature and formed) moves from the ovary to the uterus. If the egg is fertilized, it will attach to the walls of the uterus and begin to develop. Therefore, women trying to get pregnant need to do the right calculations. Pregnancy, as well as ovulation, occurs differently in each case, individually, because it depends mainly on the menstrual cycle. Let's look at how the duration of this cycle is calculated.

How long does menstruation last?

Ideally, the cycle should consist of 28 days. Menstruation should be regular and last about 3-5 days, but in reality their duration can vary between 19-35, while the monthly cycle itself can take up to 9 days.

Menstruation is a complex process directly related to hormonal balance. The slightest changes in the balance, sudden jumps caused by poor ecology, medication or stress, in any case affect ovulation and the day of conception.

Basic calculation methods

There are many ways to calculate ovulation, but, alas, none of them can guarantee that on this day the egg will leave the follicle. The fact is that this process depends on a number of factors, including irregular periods, various types of diets, hormonal imbalance, diseases, etc.

• test strips;
• ultrasound examination;
• basal (rectal) temperature;
• sensations, discharge;
• special online calendar

Let's take a closer look at each of the methods.

Method number 1. Test strips

Now, to calculate the day of conception, you can use special test strips, which can be purchased at any pharmacy. These strips are used in the same way as pregnancy tests and respond to luteinizing hormone, which appears 1-1.5 days before the egg leaves the follicle.

Note! If the cycle is regular, then the test should be done 17 days before the start of menstruation, and if not, then it is unlikely that it will be possible to determine the period of ovulation using test strips, since the woman will not be able to choose the right time for this.

In this case, it is better to resort to ultrasound examination.

Method number 2. Ultrasound

Ultrasound allows you to determine with extreme accuracy the time of release of the egg. In addition, this method is also suitable for women with irregular menstrual cycles. Thanks to the study, it is possible to determine the development of the follicle, as well as find out exactly when the egg will leave it.

If the cycle is regular, then an ultrasound should be done three to four days before planned ovulation, and if not, then egg monitoring should begin four days after menstruation and be carried out every few days.

Method No. 3. Basal temperature (BT)

The lowest temperature in the human body is considered to be basal temperature, which is observed during sleep. Its measurement makes it easy to determine ovulation, since the latter increases the indicators by approximately ½ degree.

During different periods of the cycle, women's temperature indicators are different. So, in the initial phase, BT is quite low, the reason for which is the effect of estrogen. And such conditions are ideal for preparing the egg for fertilization. The average temperature at the initial stage varies between 36.3ᵒC and 36.5ᵒC, although it can vary in one direction or the other by about 0.1ᵒC. But during the period of ovulation, this indicator increases and can range from 37.1ᵒC to 37.3ᵒC. This temperature will remain until your period. And if they have not started, and the temperature continues to remain at this level for more than 18 days and without any delays, then pregnancy has already occurred.

Note! When measuring BBT, you need to adhere to a number of rules that allow you to calculate ovulation with extreme accuracy.

1. For all measurements you need to use one mercury thermometer. It should always be kept at hand (preferably under the bed), since getting out of bed or sudden movements are unacceptable before measuring BT.
2. The procedure should be carried out every day at the same time - after waking up.
3. The measurement process itself will not cause any difficulties: the thermometer is inserted into the rectum, after which you need to lie quietly for five minutes. Then the obtained data fits into a special chart.

For the indicators to be reliable, BT must be measured only after a long (at least 6-hour) night's sleep. Distortion of indicators can occur not only if these rules are violated, but also under the influence of other factors - illness, medication, evening sex, fatigue, alcohol consumption, etc. All this must also be indicated in the schedule.

Note! A correctly drawn up chart will be able to show the absence of ovulation or its onset. If pregnancy is planned, BT is measured during three to four menstrual cycles. All this will allow you to determine the cherished day of ovulation.

Method number 4. Sensations and discharge

Sometimes the ovulation period can be determined without resorting to any calculations. For some women, it’s enough to listen to their body. During this period you may experience:

• short-term aching pain in the lower abdomen;
• change in vaginal discharge (it becomes viscous and more abundant);
• breast enlargement;
• high sexual activity;
• mood changes.

Discharge during the ovulatory period becomes abundant, transparent and viscous, resembling the consistency of egg white

Method No. 5. Online calendars

Today, on many resources you can use special programs that allow you to determine the most favorable time for conception. These programs are based on the so-called calendar method of contraception. According to them, if the menstrual cycle is normal, that is, it lasts 28 days, then 12-16 days from the beginning of menstruation are optimal.

To create an individual ovulation calendar, you should enter the duration of your menstrual cycle (usually 28 or 29 days) and the exact date of your last period in the required fields, and then click the “Calculate” button.

Do not forget that the beginning of the cycle can only be considered the first day of menstruation.

Video - How to calculate ovulation and day of conception

As you can see, calculating ovulation is not as complicated a procedure as it might seem at first glance. To do this you only need to know:

• duration of the monthly cycle;
• date of the last critical days.

By determining your ovulation period, you will know which days are suitable for conception and which days are safe for sex.

Table. Signs of ovulation, cycle, changes

Video - Determining ovulation

More and more young families are taking a responsible and conscious approach to planning pregnancy and childbirth. To find out on which days of the next cycle the possibility of conception is especially high, it is always useful to calculate the ovulation calendar, that is, the exact date when an egg ripe for fertilization will leave the follicle. Two to three days before this date and 24 hours after the onset of ovulation are the most “fertile” moments, when the possibility of a meeting between sperm and egg is maximum. The lifespan of an egg is approximately 12-36 hours, but

sperm are more durable. By the time of ovulation, the hardiest of them can already be waiting for the egg in the right place, if sexual intercourse took place even a few days earlier. That is why the favorable period for pregnancy lasts several days.

Sometimes married couples try to calculate the ovulation calendar for the opposite purpose: so as not to protect themselves from unwanted pregnancy on other days. Gynecologists still do not recommend using this method of contraception, since it is very unreliable: even in a woman who has a constant menstrual cycle, ovulation may shift by a couple of days in one direction or another from its expected date.

Calculate ovulation calendar online

In order not to count on your fingers, we suggest using our service and freely calculating the ovulation calendar online for any month of any year. This is very easy to do: you just need to remember when your last period started. This date - day, month, year - must be entered into the appropriate calculator window, as well as indicate the average duration of your menstrual cycle and the number of cycles for which you want to calculate the ovulation calendar. This service allows you to determine the expected date of ovulation a year in advance.

Our calculator will quickly do the calculations and determine when you are expected to ovulate in the next month or any other month/cycle you specify.

However, do not forget that the calculations are always approximate (although the probability percentage is quite high). The processes of egg maturation in each menstrual cycle can be influenced by many factors, but in general, in order to determine the most favorable days for conception, this method is quite suitable.

Let your expectations come true, whatever they may be!
