How to find out your ovulation date online. Calculate ovulation. Physiological signs of ovulation

Ovulation and conception calendar is a universal and fairly easy-to-use service designed to calculate the menstrual cycle and the most favorable period conceiving a child. Its main task is to help a woman determine the days of increased fertility ( ovulation), during which conceiving a child most likely. At the same time, thanks to the calculation of the so-called “safe days”, ovulation calendar allows her to avoid unwanted pregnancy without the use of any medications or mechanical contraceptives. In order to take advantage ovulation calendar and calculate your own menstrual cycle (favorable period conceiving a child), fill in all the fields of the form below one by one. Registered and authorized users of our Internet portal can save their personal ovulation and conception calendar in the “favorites” section of your personal account and return to it later.


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 probability 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.

In this work you can find the answer to the most common question of girls dreaming of having a child: how to recognize ovulation? There are times when a couple has quite active sex, but the long-awaited result still does not come. What to do in this situation? Of course, you can sign up for quite expensive procedures and try to find out the reason there. But maybe it's because you're just having sex at the wrong time?

As you know, conception is possible only at the moment the egg leaves the follicle. This process is commonly called ovulation. Today we will talk about how to recognize ovulation not only with the help of specialists, but also independently, at home.

When is fertilization possible?

Before we look at all the possible methods, we suggest you get a little familiar with the process of fertilization of an egg and the process of ovulation. It is also important to point out that the question of how to recognize ovulation also plagues those women who seek to avoid pregnancy.

In order to answer the main question, you need to get acquainted a little with female physiology. Ovulation occurs almost every month if the girl is of reproductive age and healthy. As a rule, the probability of pregnancy is only about two days a month. These days fall in the middle of the menstrual cycle. Here are some approximate calculations:

  • 28-day cycle - ovulation occurs on the 12th day;
  • 35-day cycle - on the 17th day.

It should be taken into account that everyone’s body is individual, you need to listen carefully to your body, then you will not be able to miss the moment of ovulation.

What is this?

Now we will tell you a little about what ovulation is. This concept is very important for girls who dream of getting pregnant. The ovulation process is of great importance when planning pregnancy. After all, if it does not happen, then pregnancy is impossible.

To put it briefly and in accessible language, ovulation is the process of an egg leaving the follicle that is fully mature and ready for fertilization. It lasts only a couple of minutes; as soon as the mature egg enters the abdominal cavity, the ovulation process is considered complete.

Even in prenatal development, girls lay eggs; there are about a million of them. Until puberty, the eggs remain dormant. However, some of them die without waiting to emerge from the follicle. By the time of her first menstruation, a girl has about 300 thousand follicles. Of this number, only about 500 ovulate during the entire reproductive period.

In order to answer the question of how to recognize ovulation, it is necessary to clarify the fact that ovulation may not occur every month. However, there are cases when several follicles mature and burst at once. If this happens, then a multiple pregnancy is possible.

Methods

From this part of the article you can learn how to recognize ovulation on your own or with the help of specialists. There are several methods in total:

  • ultrasound diagnostics;
  • blood analysis;
  • rapid test;
  • listen to feelings;
  • observe vaginal discharge;
  • construction method

The most accurate result will be one confirmed by several methods for recognizing ovulation. However, some of them can take a big toll on your wallet. For example, if you go for an ultrasound every day or use rapid tests. The most correct option is to calculate the approximate days of ovulation using the calendar method, confirm or refute your calculations using a test strip.

Ultrasound

In this section you will learn how to recognize ovulation by ultrasound. Ultrasound examination is carried out in a number of cases, from determining the cause of an irregular cycle to diagnosing infertility.

A gynecologist may prescribe an ultrasound to track ovulation if there are the following problems:

  • painful periods;
  • their absence;
  • when stimulating egg maturation;
  • in the treatment or diagnosis of infertility;
  • if a woman is preparing for an IVF procedure;
  • with poor results of hormone tests;
  • if a woman is planning a pregnancy after an abortion, miscarriage, etc.;
  • for the selection of contraceptives.

Many people are interested in the question: how is ultrasound performed to determine ovulation? There are three methods of examination:

  • transvaginal;
  • transrectal;
  • transabdominal.

The first two methods are internal, the last is external. The most common option is transvaginal. The transrectal method is used to study virgins, and the transabdominal method is used to study pregnant women.

It has already been mentioned that the transvaginal method is most widespread. During the procedure, a sensor is inserted directly into the vagina. An ultrasound examination using this method takes no more than 30 minutes, and the woman does not experience any pain during this process.

The advantage of this examination is that you do not need to prepare for it at all. You need to shower and empty your bladder. You need to take a regular condom with you.

Blood analysis

How does approaching ovulation manifest itself? How to recognize it using a laboratory method? In this section you will find out the answers to these questions.

As you know, the menstrual cycle is impossible without the participation of many hormones. The main ones are: FSH, LH, progesterone. Let's tell you a little more about each of them.

Follicle stimulating hormone, also called FSH, promotes the maturation of follicles that are located in the ovaries. If the hormone content exceeds the maximum norm, the follicle simply ruptures, thus releasing the egg. At this moment, ovulation occurs. Then the concentration gradually decreases.

Next on our list was luteinizing hormone. This is what the rapid ovulation test is trying to identify. It is important to know that the day before ovulation the amount of this hormone increases approximately tenfold. If you decide to take a blood test for hormones to determine ovulation, you also need to know that it is important not only its presence in the blood, but also its ratio with FSH. This ratio should be approximately this: LH:FSH = 1.5:2.0. With a regular cycle, this analysis must be done on the 3-8th and 19-21st days of the cycle. FSH is also given on the same days. If the cycle is irregular, then ovulation must be monitored by taking a test daily from the 8th to the 18th day of the cycle.

The last thing we noted was progesterone. It is also called the pregnancy hormone. It received this name for a reason, the whole point is that progesterone is produced by the corpus luteum and protects the embryo from miscarriage. Its deficiency can cause infertility.

This method of determining ovulation helps not only to determine the exact day of its onset, but also to identify hormonal imbalances. It is better to combine a blood test for hormones with an ultrasound examination, so the result will be more accurate.

Now we propose to identify the pros and cons of this method. This information can be obtained from the table below.

Test strips

Now we will discuss another method. How to recognize ovulation with an irregular cycle? In fact, this is not so easy to do. You can spend a lot of time and money, go to the clinic for long studies. Regularly undergo ultrasound examinations, blood tests, and so on. There is a less expensive way.

Girls often use rapid tests to determine pregnancy, but few people know that there are similar test strips for determining ovulation. The advantage of this method is that you can carry out the test at home, on your own, and there are no significant material costs.

Prices for these express tests vary from 30 rubles to 1.5 thousand. The probability is quite high, approximately 90%.

Now a little about the method of application. First you need to decide on the day. If you have a regular cycle, subtract the number "17" from its length, then you will get the day of the cycle on which you need to test. With an irregular cycle, you need to take the length of the shortest one for the last half of the year and also subtract 17.

  • do not drink for 4 hours before the test;
  • refrain from going to the toilet 2 hours before;
  • follow the instructions specifically for your test;
  • do not use morning urine;
  • for a more accurate result, do it 2-3 times a day (the most suitable time is from 10 am to 10 pm).

Feel

In this section you will learn how to recognize ovulation by sensations. It is important to understand that you will not be able to feel the process of tearing the follicle. The reason lies in the fact that it does not have nerve endings. But the egg begins to move through the fallopian tubes as a result of their contractions, which can affect the physical and emotional state.

So, how to recognize ovulation by sensation? The following symptoms may appear:

  • slight pain in the ovarian area, it can have a different character (aching, cutting, stabbing, cramping, etc.), it lasts for 1-2 days;
  • pain after ovulation (this may indicate inflammatory processes, you need to make an appointment with a gynecologist);
  • the day before ovulation, a girl may be in a very good emotional state;
  • sexual activity increases;
  • Your mood improves and you feel more confident.

It should be noted here that each organism is individual, the signs may be different. In order to determine ovulation, you need to listen carefully to your body.

Discharge

In this section we will tell you how to recognize ovulation by discharge. It is important for all girls to know that the cervix secretes special mucus, which helps sperm survive and move through the reproductive tract. If a girl is attentive to her body, then she knows how to recognize ovulation by the discharge.

The first period after menstruation is the so-called dry period. During this period of time there is practically no discharge, as there is a low level of estrogen. There may be discharge, but it is very thick, this is necessary for the formation of a cervical plug. It is needed to prevent any infection or sperm from entering the uterus.

Just before ovulation day, estrogen levels begin to rise and cervical mucus becomes thinner and stickier. After this, it acquires a creamy texture. Such discharge is considered normal if certain conditions are met:

  • the discharge resembles jelly and is transparent in color;
  • they are observed in small numbers;
  • have no odor;
  • do not have a bad effect on the skin;
  • no itching;
  • no pain;
  • no elevated body temperature.

As the egg matures, the nature of the cervical discharge changes. One day and up to 2 days after ovulation, they acquire a consistency similar to raw egg white. Don’t worry if the discharge becomes very heavy, this is considered normal.

It is also necessary to clarify that the nature of the discharge and its duration are individual for everyone.

Calendar method

Now we will share another method on how to recognize ovulation without a test. Previously, a regular calendar was used for these purposes. The essence of the method is as follows: be sure to mark every day of menstruation for a long period of time. For a more accurate result, it is usually analyzed from 6 months to a year.

It is also important to point out that the likelihood of determining the exact day of ovulation using the calendar method is very low. How it works? Record the start dates of the last 12 menstruation, then apply the Ogino-Knaus method. First formula: A = B - 18; second formula: C = D - 11. A is the beginning of a period favorable for conception, B is the duration of a short cycle, C is the end of a favorable period, D is the duration of the longest cycle.

Basal temperature measurement

In this part of the article, you will learn how to recognize the day of ovulation using paper, a pen and a regular thermometer. This method is more accurate relative to the calendar method. In order to calculate the day of ovulation, it is necessary to analyze the schedule of at least 3 cycles.

For these purposes, basal temperature is measured using one of the following methods:

  • in the oral cavity;
  • in the rectum;
  • in the vagina.

Since temperature must be measured every day (even during menstruation), the most optimal option is to measure it in the rectum.

To calculate, you must adhere to the following recommendations:

  • measure temperature daily;
  • if you use the oral method, then the thermometer should be held under the tongue for at least 5 minutes, while pressing your lips tightly;
  • if you use the vaginal or rectal method, you need to insert about 3 centimeters and measure the temperature for 4 minutes;
  • always use the same thermometer;
  • you need to measure your temperature in the morning without getting out of bed;
  • record the obtained result in a special chart.

Reading the graph

In the previous section, you learned how to recognize ovulation at home using a thermometer. Now a little about how to read the resulting graph.

From the first day of menstruation, the basal temperature is high; in the middle of the cycle it decreases. It is necessary to look for ovulation around this period. It can be recognized by a jump from 0.2 to 0.6 degrees. After this drop, the temperature will remain at this level for up to 2 weeks. On the eve of menstruation, the temperature drops. The day of ovulation is considered to be the day when the basal temperature is lowest before the jump.

Now you can easily predict the day of ovulation. The most favorable period for conception is two days before the jump and the day after it.

Problems with conception are quite common today, and this also applies to absolutely healthy young couples.

Stress, strong emotional disturbances, a sedentary lifestyle, bad habits, excess weight and many other factors can contribute to this.

Even poor nutrition can cause a long-awaited pregnancy to never occur. If a man consumes few foods containing zinc, selenium and chromium, the activity of his sperm drops sharply, they lose viability, and the overall quality of sperm deteriorates.

If the spouses are healthy and do not have chronic diseases, then the method of determining ovulation can help speed up conception. Determining the most favorable day for fertilization has long been used in IVF clinics and reproduction centers, but this does not mean that a woman cannot independently calculate the day of ovulation.

Ovulation is the release of mature eggs from the follicle into the cavity of the fallopian tube. This is where fertilization occurs if the sperm reaches its goal. It is important to understand that the lifespan of an egg outside the ovaries is no more than 24 hours, so women who want to get pregnant should not miss this opportunity.

Ovulation occurs only once a month, however, there are cases when eggs come out of the follicles only 8–10 times per year instead of the required twelve. Most often, this occurs in women with an inconsistent menstrual cycle, as well as disturbances in the functioning of the endocrine system.

All girls and women who are sexually active and cannot get pregnant within a year are recommended by gynecologists to keep an ovulation calendar, which allows, even with an error, to calculate the day of conception. This will help determine favorable days for conception and prepare for pregnancy in advance (3-4 days before expected ovulation, you should abstain from intimacy and follow a special diet).

There are many methods to determine the day of ovulation. They all have their pros and cons, so you shouldn’t stop at just one. After all, the more accurate the result obtained, the greater the likelihood of pregnancy. So, on what day does ovulation occur?

How to calculate the day of ovulation if you have a regular cycle

Last period method

This method allows you to determine on what day after menstruation ovulation occurs. This is the simplest, but at the same time the most unreliable way to determine ovulation.

The day of expected menstruation is 14 days = ovulation.

In order to determine the expected day of the onset of menstruation, you need to add the average cycle length (from 27 to 37 days) to the first day of the last menstruation. Subtract 14 days from the resulting date - this will be the estimated date of ovulation.

28 days – cycle duration

Total: March 15 is the expected day of thinning of the ovarian walls and the release of mature eggs, that is, ovulation.

Calendar method for determining a favorable day for conception

A slightly more accurate way to determine exactly when the period favorable for conception will occur. To do this, you need to know all the cyclic dates for the last six months, or even better - for the year. Next, you need to make calculations using the following algorithm:

  • Determine the duration of the longest and shortest cycles.
  • Subtract 18 from the shortest one. The resulting figure will be the date of the beginning of the fertile (favorable) period.
  • Subtract 11 from the longest one. The resulting figure will be the end date of the fertile period.
  • The interval between these values ​​is the period when the probability of conception increases by 50–70%.

The described methods are effective only under one condition - the menstrual cycle is constant, and the woman monitors its duration (knows exactly the start and end dates of menstruation) for at least 6 months.

If your cycle is inconsistent, you can determine ovulation using other methods.

With an irregular cycle

Basal temperature measurement

- This is the lowest temperature of the human body, which is measured during rest. You need to measure it in the morning, before getting out of bed. It is best to measure the temperature in the rectum (anus), although you can insert the thermometer into the mouth (under the tongue) or into the vagina.

Measurements must be carried out for at least three months. This is important for the reliability of the data obtained and the accuracy of the graph. The data should be recorded in a special notebook, preferably so that you can clearly record the curve of the rise and fall of the values.

The thermometer should be held for at least 5 minutes, and measurements should begin on day 1 of the cycle.

How to decipher the result?

  • During menstruation, the temperature will be quite high, after which it will decline (this usually happens towards the middle of the cycle).
  • At the moment of ovulation, basal temperature values ​​rise sharply by 0.2–0.6 degrees. Such values ​​can last up to two weeks.
  • Before the next monthly period, the thermometer will drop again.

The lowest temperature values ​​recorded before the next increase will be considered ovulation.

Ovulation tests - help you get pregnant

The most popular and fairly reliable method for determining ovulation.

The principle of operation of these tests is similar to similar strips for determining pregnancy, which are used when there is a delay to confirm or exclude the possibility of pregnancy.

The only difference is that ovulation test strips determine the content of LH (luteinizing hormone) in the urine, which reaches its maximum concentration 24 hours before the eggs leave the follicle cavity.

These tests must be carried out every day during the fertile period - this is the only way the accuracy of the result will be close to 98%.

Saliva testing: the “fern” method

At the time of ovulation, the amount of female hormones - estrogens - increases. Under their influence, the composition of the salivary secretion changes, in which the level of sodium chloride (salt) almost doubles. If you apply such saliva to glass on the day of ovulation, then as it dries, you will see a pattern similar to fern leaves. Small salt crystals form on the surface of the glass - this picture can be observed 72 hours before and after ovulation.

There are special devices on sale for carrying out such testing. They are convenient and easy to use, and the accuracy of the results obtained ranges from 90 to 96–97%.

Ultrasound monitoring

The most reliable method that allows you to accurately calculate the day of ovulation to increase the likelihood of conception. Ultrasound monitoring (folliculogram) is a dynamic observation of the growth and maturation of follicles and the expulsion of eggs.

This study is called monitoring, as observation is carried out over time. This means that the frequency of examination using a transvaginal sensor is every day for the period necessary to establish a diagnosis or confirm the fact of ovulation.

This method is used in the treatment of infertility and IVF, since only with the help of a sensor can one assess the condition of the organs of the female reproductive system and determine whether positive dynamics occur in response to therapy as part of artificial stimulation of ovulation.

Constant monitoring is also necessary for polycystic ovary syndrome, and in some cases with this disease, the study can be carried out for 3 months in a row (with two-week breaks).

What can be assessed using ultrasound monitoring:

  • growth and maturation of the dominant follicle on the eve of ovulation;
  • the appearance of free fluid after ovulation;
  • destruction of the walls of the main follicle;
  • formation of the corpus luteum at the site of maturation of the dominant follicle.

For the first time, the patient should come for the study on the 6th day of the cycle; in the future, the procedure will be repeated every day until ovulation occurs. A control ultrasound should be performed no later than 3 days after the date of release of the eggs from the cavity of the dominant follicle.

Among the listed methods for determining ovulation, there are none that would 100% guarantee an accurate result. Even during ultrasound monitoring, small errors are possible, since there is a human factor, and the possibility of error cannot be completely eliminated. However, using these methods, you can increase the chances of a successful conception by at least half, so you definitely shouldn’t neglect them.


Calculation of the day of ovulation, menstrual cycle and days favorable for conception and pregnancy.

Using this calendar you can calculate the days ovulation, that is, 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 will receive a menstrual calendar for 3 months, which will indicate: ovulation day, days favorable for conception, days to conceive a boy and a girl. Do not confuse the duration of menstruation (period) and the duration of the menstrual cycle! Interactive ovulation calendar: hover over a day on the calendar and read additional information.

Notes
. When you hover over the days in the calendar, additional information will appear. The duration of the menstrual cycle and the duration of menstruation itself are different things. The duration of menstruation or "period" is individual and usually lasts 3 days and does not affect ovulation day. If menstruation takes less than 2 or more than 7 days, you need to contact gynecologist. The average cycle duration varies from person to person. (usually from 21 to 35 days) How to calculate the length of the menstrual cycle: from the day of the end of the previous ones to the day the next “menstruation” begins. Typically this is 28 days. The first day of your period is the first day of the menstrual cycle.

Color coded
period
ovulation day the likelihood of getting pregnant is high (conceiving a boy)
the probability of getting pregnant is average (conceiving a boy)
the probability of getting pregnant is average (conceiving a girl)
the chance of getting pregnant is slightly lower
the probability of getting pregnant is low (conditionally safe days)

Topic of this page: ovulation calendar free, ovulation test, ovulation, ovulation chart, time of ovulation, how to calculate “safe” days?, is it possible to get pregnant immediately after menstruation (you can!). Ovulation - the readiness of the egg for fertilization - occurs approximately in the middle of the menstrual cycle. The egg can be fertilized within a short time, this period is from 12 hours to two days. All this time, the female reproductive cell moves towards the uterus, where the development of the future fetus should occur; it is at this stage that the meeting with male sperm should occur. Considering that sperm, once in the fallopian tubes, can remain viable for up to 5-7 days while waiting for an egg, conception is possible even if sexual intercourse was a week before ovulation, and by the way, this day may be immediately after menstruation. The ovulation period is the most favorable time to conceive.




One of the ways to plan is to choose the right time conception– Shettles method. This method is based on knowledge of the lifespan of male sperm in a woman's reproductive tract. Sperm can remain active for up to five days, so couples can conceive a child by having intercourse before the release of the egg (ovulation). If you want a daughter, plan sexual intercourse a few days before ovulation, son, plan sex 12 hours before ovulation. At irregular cycle other methods of determination should be used ovulation, For example, BT (basal temperature). Please add this page to social networks and blogs.

You can also use the alternative ovulation calculator.

Ovulation - the readiness of the egg for fertilization - occurs approximately in the middle of the menstrual cycle. If menstruation occurs every 28 days, then ovulation occurs around day 14. If your cycle is shorter (for example, 21 days) or longer (about 35 days), ovulation can be expected on days 8-11 or 16-18 of the cycle, respectively. Our ovulation calculator will help you accurately calculate the day of ovulation, and will also show the probability of pregnancy on each day. Also carefully read the notes at the bottom of this page. The most fertile days during each cycle (the days you are most likely to become pregnant through unprotected sex) include ovulation day and the days before. These are the days of maximum fertility. High ability to conception also observed for several days before. At this time you also have chances of getting pregnant. Outside of this “fertility window,” which lasts about six days, the chances of getting pregnant are very low.

Ovulation is the release of mature eggs from a woman’s ovary. After leaving the ovary, the egg can be fertilized within 12 to 24 hours, unlike, by the way, the sperm, which lives 3-5 days. Therefore, if you want to get pregnant, it is important to understand exactly when ovulation occurs in order to plan conception for the “fertile period” (days favorable for conception).

How to find out when ovulation occurs?

To calculate ovulation, subtract 14 days from the time of a woman's monthly menstrual cycle (usually 28 days) (i.e., the duration of the luteal phase). For example, if your cycle is 29 days, then ovulation will most likely occur on the 15th day of the cycle. If you have a 24-day menstrual cycle, then expect to ovulate on the 10th day.

Unfortunately, this method will not help if you do not have a regular monthly cycle. Therefore, if you are having problems determining the date of ovulation, visit your doctor, who will give advice specifically for your case.

Measure your basal temperature with a menstrual cycle chart

Measuring basal temperature will also be very useful in determining the day of ovulation. To do this, you will need a basal temperature table, which you can download and print from the following link:

When completed it looks like this:

Determining the day of ovulation using a completed menstrual cycle chart is not difficult. Usually, right before ovulation, the temperature drops slightly, and then, on the contrary, rises, and remains this way until the end of the menstrual cycle. Using this method comes down to measuring temperature for 2 months, after which it becomes possible to calculate the approximate date of the next ovulation, and then plan sex 2-3 days before it.

Basic rules for measuring basal temperature:

  • Take your temperature every morning at the same time (+/- 30 minutes).
  • It is not recommended to get up, sit down, walk or even go to the toilet before taking your temperature. The very minute after waking up, take the thermometer in your hands.
  • Use the same thermometer. If you bought a new one, measure with it at the start of your next menstrual cycle.

Monitor your body's other "signals"

On the day of ovulation, you may experience discomfort or mild pain in the abdominal area that lasts for several hours. In general, some women easily determine their ovulation, while others are not even aware of it.

  • Have sex more often. The best chance of conceiving is when you have sex 1-2 days before ovulation, however, your cycle may not be regular, which is why you may very well “miss the mark.” Sperm can survive in a woman's body for up to 5 days, so to get pregnant, have sex every day, starting 3 days before ovulation and 2-3 days after it.
  • Don't rush to the bathroom after sex. Lie in bed for a few minutes after intercourse.
  • Do not use artificial lubricants, vaginal sprays, scented tampons, or douching. They can disrupt the normal acidity of the vagina.
  • Reduce your stress levels. Research shows that high levels of stress can interfere with conception. We do not recommend quitting your job or making major changes in your life. Simple things like a walk in the park, exercise, or hugging a loved one can help reduce stress.
  • Try to maintain a healthy weight. Experts also advise keeping an eye on your weight, since being underweight or, conversely, being overweight can lead to disruption of ovulation and also negatively affect the body’s production of key reproductive hormones.
  • Do you want a boy or a girl? Unfortunately, there is no natural way to select the sex of an unborn child, but scientists have found that “female” sperm live on average longer than “male” ones. Therefore, to conceive a boy, plan sexual intercourse as close as possible to the moment of ovulation, but if you want a girl, then on the contrary, plan to have sex 3-4 days before ovulation, then there will be more “female” sperm around the egg, and accordingly the chances of conceiving a girl will be higher.
