The menstrual cycle is 29 days when ovulation occurs. When does ovulation occur after menstruation - when can you get pregnant? Why is it important to know what day ovulation occurs?

Ovulation is the moment when an egg leaves the follicle. It stays in the tubes for no more than 2 days, after which it moves into the uterine cavity. If it encounters a sperm on its way, fertilization occurs. Already in this form, the egg attaches to the endometrium of the uterus, and pregnancy begins. Fertilization can only occur at the moment of ovulation. For this reason, every woman tries to calculate this day in her cycle. While pursuing completely opposite goals. Some people want to get pregnant, others want to avoid conception. When does ovulation occur after menstruation?

A healthy woman under 30 years old has 1–2 cycles where ovulation does not occur. It is considered normal because this is how the reproductive system rests. After 35 years, the number of such menstrual cycles without ovulation increases to 6. Knowing the average duration of cycles per year, we can only guess the approximate date of ovulation. What is necessary for ovulation to take place?

At the beginning of the menstrual cycle, an egg is born, but not just one, but a large number. They develop in the follicles of one of the ovaries. Within a week, one of them is significantly ahead of the others in development and becomes dominant. And after a certain time, the follicle bursts, releasing the egg. The sex hormone estrogen is responsible for this entire process. Its amount increases immediately from the first day of the menstrual cycle. Development of the egg occurs in approximately 11–15 days. When the follicle reaches its maximum size, estrogen levels decrease and the amount of progesterone increases sharply. This surge in hormones leads to rupture of the follicle. Progesterone is responsible for the further development of the egg.

Ovulation lasts from 12 hours to 2 days. Depends on the individual characteristics of the body, the hormonal background of the woman. After ovulation ends, the second part of the menstrual cycle begins. It is no longer possible to get pregnant. It is possible to determine exactly when ovulation will occur approximately and with certainty. There are several calculation methods. First of all, the calendar calculation method is taken into account, based on the duration of each menstrual cycle.

Ovulation in a 28 day cycle

Doctors call this duration the most ideal. The beginning is the first day of the previous menstruation. The cycle ends on the first day of the next menstruation. Under such conditions, the egg develops for 13 days. After menstruation, ovulation occurs 1.5–2 weeks later. Depending on the duration of menstruation itself – 3–5 days. Ovulation occurs on the 14th day of the menstrual cycle. Its duration also depends on the individual characteristics of the body. Usually this is a day. But one more day is taken in reserve. After ovulation, 12 days pass and menstruation begins.

Ovulation in a 30 day cycle

The duration of the menstrual cycle of 30 days is also considered within the normal range. Calculating the moment of ovulation is also quite simple. The duration of the luteal phase – the second – is 14 days. Then 14 is subtracted from the total duration of the cycle. In an example, it looks like this: 30–14 = 16. The process of egg development lasts 15 days, ovulation occurs on 16. After menstruation, ovulation occurs 1.5–2 weeks later.

Ovulation in a 26 day cycle

In a short cycle it happens in a similar way. The luteal phase lasts 14 days. These days must be subtracted from the total duration of the menstrual cycle. 26–14 = 12. The egg develops for 11 days, on the 12th the egg leaves the follicle. After menstruation, ovulation occurs approximately a week later.

Reasons for different cycle lengths

Taking into account the fact that each organism is an individual system. The normal duration of the menstrual cycle is 28–32 days. All processes in a woman’s body occur under the influence of hormones. Various factors upset the balance. They delay menstruation or cause them to arrive prematurely.

Coordinates the production of hormones by the brain and central nervous system. They send signals to internal organs about the amount of necessary sex hormones. They are produced by the thyroid gland, ovaries, and adrenal glands. Their work is affected by the defective functioning of the digestive organs, kidneys, and liver. The balance can be disrupted by harmful environmental conditions, poor quality nutrition, a sedentary lifestyle, a woman’s weight, physical and emotional stress. Taking into account all these factors, the optimal duration was compiled. Even deviations in one direction or the other for 2 weeks are considered normal under certain conditions.

How to determine ovulation for sure

If the previous method is based on theoretical data, the following ones use practical ones.

Basal temperature measurement method

In the first half, temperatures remain between 36–36.6 degrees. A day or 12 hours before the start of the ovulation process, the temperature drops by several degrees. And immediately the next day there is a significant upward jump. This jump allows you to determine the moment when the egg leaves the follicle. In the process of increasing the amount of progesterone in the body, heat is released, which provokes an increase in basal temperature. Ovulation occurs at a temperature of about 37 degrees. After this, there may be a slight increase, decrease, or remain at the same level. How the egg develops further depends on fertilization.

If conception has occurred, after the ovulation period, another slight jump in temperature occurs - the moment of implantation. Then the temperature continues to remain within 37. This is how pregnancy is determined.

The method is widely used in gynecological practice. Despite all its simplicity, it is the most informative. In combination with the calendar, you can accurately determine when the days of egg release occur. Observations must be carried out for 3 months, and in case of an irregular cycle from 6 to 12.

Ovulation test

Similar to a pregnancy test. Urine is used as the material for analysis; in modern models, saliva is used. The morning urine sample is not suitable for this purpose. To determine when ovulation occurs, you first need to calculate the length of your cycle. Using the calendar method, it is necessary to determine the moment of release of the egg. So, with 30 days it will be day 16. The study should begin at approximately 11 days. The analysis is carried out every day until the test shows the desired result. If more than 10 days have passed, there will be no ovulation period. Further research needs to be continued in the next cycle. If there are no alarming symptoms, there is nothing to worry about. But if the situation repeats for more than 3 months in a row, you should seek help from a doctor. Then, to determine when ovulation occurs and whether it occurs at all, another method is used.

Ultrasound examination of the ovaries

The method is absolutely painless; a woman does not need to prepare specifically for it. Research is carried out every day. First, the presence of a dominant follicle is determined. Then its development. The method allows you to see the moment when the ovulation period is about to begin, which is very helpful for couples who cannot conceive a child for a long time. If there is no rupture of the follicle, observation is stopped. The woman needs to undergo hormonal therapy and continue trying to conceive again. To prevent pregnancy, the ultrasound method is not used. In this case, measuring basal temperature is available.

On what day can you get pregnant?

A modern educated woman knows that you can get pregnant on any day of the cycle, provided that ovulation occurs. And it can appear at the beginning of the cycle, at the end, on critical days. It's all about hormonal levels and factors that affect a woman's body. Theoretical calculation is based on approximate data. If the cycle is irregular, its average value should be calculated. It is necessary to add up the entire duration over six months, a year. Divide by 6 or 12. For example, 26+28+30+25+32+35 = 176, divide by 6 = 29. The resulting duration is 29. From this number you need to subtract 14. It turns out that on the 15th day the egg is released from the follicle . But everything is approximate.

The following calculation method suggests taking days with a reserve. A woman must subtract 17 days from her shortest monthly period and 11 days from her longest period. It turns out to be a period of days favorable for conception. 25–17 = 8; 35–11 = 24. From 8 to 24 days you can get pregnant.

If a woman has regular periods, days favorable for conception are much easier to determine. This is 5 days before the ovulation period and 2 days after it. Although the egg is capable of fertilization for only 24 hours, or even less, the viability of the sperm is also taken into account. They remain active for about a week on average. That is, sexual intercourse a week before the release of the egg can cause pregnancy.

Discharge before ovulation period

Ovulation occurs with certain symptoms. You should pay attention to your own feelings and the nature of the discharge. Many women feel a nagging pain in the lower abdomen, in the area of ​​the ovaries. A little pain radiates to the back. Libido and mood increase, vital activity increases. The discharge during the ovulation period is transparent, viscous, sometimes mixed with blood. White thick or brown. Always in greater quantities than before. You can determine when the egg is released by carefully monitoring your body every day.

The ovulation process is a rather complex system. It is important for a woman to know when it occurs and whether it exists at all. At a certain point, she has a desire to have a child. Then difficulties may arise with this process. Regular periods are considered the key to women's health. If there is no ovulation, then there are significant hormonal disorders and pathologies in the reproductive system. The woman will undergo a long, thorough examination and, if necessary, therapy. Deciding on the release of an egg after 35 years is much more difficult. Then you should seek help if a woman has not been able to conceive a child within 6 months. Or pregnancy occurs, but constantly fails.

Otherwise, when ovulation occurs, the process is purely individual. You should study your body and observe changes in each phase from the moment your menstruation begins. Then any deviation will be immediately noticed.

Ovulation refers to certain days when the female body is most predisposed to fertilization. That is why it is very important for everyone who dreams of a long-awaited pregnancy to know all the features of this natural process, as well as to be able to calculate the day of ovulation.

Ovulation and conception calendar online

Calculating ovulation online is one of the fastest, most accurate and effective ways to determine fertile (favorable for conception) days yourself. To do this, a conception calculator is used, which calculates and displays fertile days over a period of four months.

To calculate ovulation online, you must enter the following data:

• First day menstrual bleeding of the cycle you are interested in (if you are interested in the days of ovulation in this and the next three months, then you must enter the first day of the last menstruation; if you want to find out which days of the previous cycles you ovulated, you must enter the first day of menstruation of the corresponding cycle);
• Average duration of menstruation;
• Duration of a regular cycle. If the cycle irregular, it is necessary to first analyze the duration of the cycle for the last 6 months, and determine the minimum and maximum number of days of the cycle. We tick the “irregular cycle” box, enter the minimum number of days of the cycle in the left window, and the maximum in the right window that appears;
• The duration of the corpus luteum phase, which is usually determined by a laboratory method based on the level of the hormone progesterone, averages 12-16 days (the default duration in the program is 14 days).

After this, you just need to click the “Calculate” button, after which the program will display an exact calendar, which will indicate the days of expected ovulation (with percentage probability), as well as the days of safe and conditionally safe sex. Ovulation online using such a calculator is calculated with fairly high accuracy.

How does ovulation occur?

Normally, a woman's menstrual cycle, which is counted from the first day of bleeding to the first day of the next period, lasts from 28 to 35 days.

On average, favorable days for conception (also called fertile days) occur in the middle of the cycle, and include 1-2 days before ovulation, the ovulation period itself and 1 day after ovulation. The average duration of the fertile state is 7 days.

That is, the fertile period begins at the moment of a jump in LH levels. If during this time the sperm does not fertilize the egg, it simply dies, and a new one matures only in the next cycle.

Corpus luteum phase (luteal phase)

After the end of ovulation (follicular phase), the maturation period begins corpus luteum - luteal phase, which is characterized by a decrease in the level of the hormone LH and an increase in the production of progesterone. The corpus luteum is responsible for the production of hormones necessary to maintain the normal course of pregnancy. If pregnancy does not occur, the corpus luteum dies, progesterone levels decrease, which provokes the onset of menstruation.

Normally, the duration of the luteal phase ranges from 12-16 days. Insufficiency of the corpus luteum phase (duration of 10 days or less) or its duration of more than 16 days indicates hormonal disorders, which may result in early pregnancy loss.

Let us remember that the corpus luteum phase begins the day after the end of ovulation and lasts until the onset of menstruation. That is, to calculate the duration of the corpus luteum phase, you need to know the duration of your menstrual cycle, the middle part of which falls on ovulation, and the days following it - on the luteal phase.

In a healthy woman, ovulation occurs every month (and sometimes twice), but there are two to three months a year when the egg does not mature - such cycles are called anovulatory, and they are also considered a variant of the norm.

Having determined favorable days for conception, calculating the optimal number of sexual intercourses during this period will be quite simple, and the chances of getting pregnant will increase significantly. It should be noted that the ovulation chart will also be useful for those who want to prevent unwanted pregnancy, because it is often used as a method of contraception.

How to calculate the ovulation calendar?

Physiological signs of ovulation

Gynecologists say that every woman can notice the signs of ovulation and calculate conception - to do this, you just need to carefully monitor your body.

• Features of discharge. Vaginal discharge is a constant occurrence in every woman, but in different phases of the menstrual cycle it has a different character. So, before ovulation they become transparent and liquid, or viscous, and the consistency resembles the white of a chicken egg. In addition, during this period, some women experience brownish or bloody discharge (so-called spotting). If ovulation has not occurred, the discharge is sticky, creamy or completely absent.
• Discomfort in the lower abdomen. The release of the egg may be accompanied by unpleasant sensations in the area of ​​the ovary in which the dominant follicle matured. They can last from a few minutes to several days, and resemble the “tugging” of the abdomen before menstruation.
• Swelling and pain in the mammary glands. Under the influence of hormones, many women's breasts may become sensitive or sore before the release of an egg.
• Increased libido. Scientists have proven that it is on the eve of ovulation that women experience the greatest sexual desire - this is explained by the natural instinct of reproduction (thus the body tries to increase the chances of pregnancy).
• General changes in health. Such signs are individual for each woman - this may be an exacerbation of taste and olfactory sensations, increased performance, or, conversely, irritability and increased emotionality.

Calendar method

First of all, it should be noted that each woman has an individual conception calendar, which can be calculated based on the characteristics of the body.

With a regular cycle, if your periods literally go by the clock, the question of how to calculate ovulation usually does not pose a big problem, because for this you will have to carry out the simplest calculations. For example, if a woman’s cycle lasts 28 days, you can simply divide this figure by two: 28/2 = 14. That is, in this case, days starting from the 12th will be considered fertile.

However, this method cannot be called extremely accurate. Very often, for a number of reasons, the menstrual cycle can be shortened or lengthened; accordingly, the timing of the release of the egg also shifts, and when it is completely ineffective. That is, it is best not to rely on your own calculations, but to use a more convenient online ovulation calculator or measure your basal temperature.

Basal temperature

Measuring basal temperature (BT) is one of the most effective methods that is best suited for women with irregular cycles. To understand how to calculate the day of ovulation in this way, you should know some features of the female body.

During the menstrual cycle, basal temperature changes several times - this occurs under the influence of hormones. At the beginning of the cycle it is quite low, and during ovulation it increases significantly, reaching 37-37.3 C, and remains at this level until the next menstruation. True, to accurately determine the days of conception, it is very important to follow a number of rules:

• You need to take your temperature in the morning at the same time, after a full night's sleep (at least 6 hours), without getting out of bed.
• Use the same thermometer, preferably mercury.
• The thermometer is inserted into the anus, vagina or placed under the tongue, after which you need to lie quietly for 5 minutes.
• To obtain accurate results, BT should be measured over at least two cycles and the results recorded.

It should be noted that in this way you can calculate ovulation online. There are special resources and programs on the Internet that calculate fertile days automatically (a woman only needs to enter her BT indicators there daily).

Read more about measuring basal temperature in the section.

Ovulation test

Ovulation tests are special strips similar to those used to detect pregnancy. True, the marker in this case is the LH hormone, not hCG. Measurements are carried out in a similar way (immersing strips in urine), and should begin 2-3 days before expected ovulation.

The instructions for the test indicate which day of the cycle is best to start measuring, depending on the length of the cycle, but with irregular periods it is almost impossible to determine this time.

Read about instrumental and instrumental methods for determining ovulation

Laboratory methods

One of the ways to create an ovulation calendar, calculate fertile days and get pregnant quickly is to get tested for the main female hormones. These include:

• FSH - given on the 3-5th day of the menstrual cycle;
• LH - on days 3-8 or 21-23;
• Prolactin - on days 3-5 or 19-21;
• Estradiol - on days 4-7 and 6-10;
• Progesterone - 6-8 days.

The concentration of these hormones varies depending on the phase of the cycle, so based on the test results, you can accurately determine the day for conception.

If you ask specialists the question of how to determine ovulation most effectively, as in any cycle, the answer will be clear - monitoring follicle growth using ultrasound.

To do this, it is necessary to carry out several ultrasound procedures: the first - on the 7-8th day, the second - on the 10-12th, the third - at the request of the woman or the doctor’s recommendation. A sign of ovulation is usually the size of the dominant follicle, which is 18-21 mm. In addition, you can subsequently check whether the follicle has ruptured - if a corpus luteum has formed in its place, it means that ovulation was normal.

The name “menstruation” justifies itself. The lunar calendar consists of 28 days, just like the normal menstrual cycle. But unlike the persistent laws of astronomy, the female body chooses its own cycle. Therefore, it is worth knowing the specifics of determining ovulation in each case. Let's look at a 29-day cycle and when ovulation occurs for it.

Ovulation - when does it occur?

The menstrual cycle is the duration from the first day of menstruation to the day before the next one. The normal continuation of this period is 25-29 days, and sometimes 21-35.

It is divided into 2 phases:

• The first is follicular, in which the egg matures in a liquid vesicle called a follicle located in the ovary.
• The second is the luteal phase. It occurs after the release of the female cell and the release of luteinizing hormone.

The first period is different for each organism, but the second lasts 14 days. Between these phases of the 29-day cycle, the most important moment occurs - ovulation. This means that the egg leaves the ovary, inflicting a small wound on it, and passes into the fallopian tube to possibly meet the sperm.

Features of ovulation calculations for a 29-day cycle

Using the example of a menstrual cycle of 29 days, we will consider the features of calculations. Let’s say the first day of your period is November 3, it lasted 4 days, the next one began on December 2. We count the days up to December 1 inclusive, we get 29 days. This is the size of the cycle, which does not depend on the duration of menstruation. Even with a value of 3 or 7, the cycle is similar.

Now let's calculate if the cycle is 29 days, when ovulation is more likely. We know that the second phase is 14 days. We take our number 29 and subtract 14 from it, we get 15. This means, counting from the first day of menstruation, on the 15th day there is a favorable moment for the possible fertilization of the egg. Using this algorithm, calculations are made using other indicators.

Possible failures in the cycle

It is difficult to choose the “right” day when observing one month. After all, disruptions in the body due to stress or illness are always possible. Therefore, it is worth making a calendar at least 4–6 months in advance, and even better, keep it constantly.

To find out when ovulation occurs in a 29-day cycle, use the ovulation calendar calculation on our website.

Ovulation accounting

Also, an ovulation calendar will help in the following situations:

• will tell you when it is better to abstain from unprotected sexual intercourse due to the possibility of unplanned pregnancy;
• will warn about upcoming critical days;
• will identify disturbances in the usual rhythm, which may be a harbinger of illness. In this case, it is worth contacting a specialist in order to receive treatment in time and return to your normal routine.

All these factors will help you experience the joy of motherhood with the onset of ovulation in a 29-day cycle. Even if slight deviations are possible, strip tests contain 5-7 strips and will help check ovulation for the same number of days.

Ovulation is the moment when an egg is released from the ovary into the fallopian tube as a result of rupture of the dominant follicle. With a normal 28-day menstrual cycle, ovulation in most cases occurs on the 14th day after the start of menstruation. The lifespan of the egg is from 12 to 24 hours. The fertile period, taking into account the lifespan of sperm in the cervix (3-5 days), begins four days before ovulation and ends within 24 hours after its onset.

Normal menstrual cycle

The normal menstrual cycle is always calculated from the first day of menstruation and is usually 28 days.

Follicular phase. The first phase of the cycle begins with bleeding, the average duration of which is 5 days. After this period, under the influence of increased secretion of estrogen, the uterine mucosa begins to recover. At the end of the phase, a dominant follicle matures in the ovary from which the egg is released.

Ovulation. In a normal menstrual cycle of 28 days, ovulation usually occurs on the 14th day and continues for 24 hours. The egg leaves the ovary and, in the hope of meeting a sperm, continues down the fallopian tube.

In most cases, a woman is not able to feel the moment of ovulation. Therefore, to determine it, medical institutions perform an ultrasound of the ovary to determine the presence of a dominant follicle and an analysis of luteinizing hormone in the blood, which rises several hours before ovulation.

It will help to determine the onset of ovulation and the most fertile period, regardless of the duration of the menstrual cycle!

Luteal phase. Regardless of the length of the menstrual cycle, the third and final phase lasts for 14 days. At this time, the woman’s body begins to secrete a hormone called progesterone, which, in case of successful fertilization, prepares the uterine mucosa for pregnancy. The fertilized egg is implanted into the lining of the uterus. Under the influence of progesterone, the excitability of the uterus decreases, the growth and development of the mammary glands is stimulated, menstruation stops and pregnancy occurs. Implantation occurs 6 days after ovulation.

If fertilization does not occur, progesterone production decreases, the inner mucous layer of the uterus is rejected, and menstruation occurs after 14 days.

Signs of ovulation

To determine ovulation at home, special tests are used that measure the increased content of luteinizing hormone (LH) in a woman’s body. The production of the hormone begins to occur between 24 and 36 hours when ovulation occurs. Others include:

• and breasts;
• change in the position of the cervix.

The length of the menstrual cycle can vary among women, but ovulation, in the absence of any reproductive complications, always occurs 14 days before the start of the next menstruation.

If you have problems with the onset of ovulation, you should consult a gynecologist.

The article will tell you how to determine or calculate ovulation at home.

A woman who knows about her ovulation can allow herself to get pregnant faster or, on the contrary, protect herself from an unplanned pregnancy.

How to calculate ovulation for conception?

You can determine ovulation in the following ways:

• According to ultrasound. The procedure will not tell you the exact date of release of the egg, but it will definitely tell you about the absence or approach of ovulation
• By monthly
• By basal temperature
• According to the ovulation test
• Based on how you feel and body signals

How to calculate ovulation by menstruation?

There is a common myth that ovulation occurs on the 14th day of the menstrual cycle, i.e. on the 14th day from the start of the next menstruation. This statement is truly a myth, since the day of ovulation directly depends on the length of the menstrual cycle.

The menstrual cycle consists of two phases: the follicular and corpus luteum phase.

The second phase more or less has a general duration of 12-16 days. As you can see, the average number is really 14. But the countdown does not start from the first day of menstruation, but from the last day of the cycle, i.e. days before the start of the next period.

How to calculate ovulation with an irregular cycle?

• You cannot calculate the day of ovulation using your periods. After all, to calculate, you need to know the length of the cycle, but you cannot know this with an irregular cycle
• According to the ovulation test. The first problem with this method is that it is difficult to guess on what day to take the test. The second problem is that the test can show a false positive result. This is explained by the fact that cycle failure often indicates hormonal problems in the body. And if hormones are not produced according to standards, then the production of the hormone in larger quantities than expected can provoke a false test reaction

• According to symptoms. This method also works for irregular periods. More information about the method can be found below.

• Ultrasound. You can do an ultrasound, but with a 45-day cycle, you will have to attend many ultrasounds, tracking the dynamics of follicle growth. And this will cost you a pretty penny

• Measuring basal temperature is a fairly effective method for irregular cycles. But you should first make a chart of your basal temperature for 3 months, noting the exact readings every day. This will allow you to understand what temperature jump occurs during ovulation in your body. Read more about basal temperature during ovulation and conception below and in the article

How to calculate your ovulation cycle?

To create an ovulation cycle, you should record your cycle duration for 6 months. Based on the results, make the following calculations:

• Subtract 11 from the longest cycle
• Subtract 18 from the shortest cycle
• The period between the received days and will be the most likely for the onset of ovulation

Example.

The longest cycle was 36 days. Do simple calculations: 36-11=25 day of the cycle.

The shortest cycle was 28 days. 28-18=10 day of the menstrual cycle.

This means that the most likely period for the onset of ovulation and conception in a particular woman is the interval between the 10th and 26th day of the cycle. That is, there are 16 probable days for it.

Ovulation test

Detailed information about ovulation tests is presented in the article

Basal temperature during ovulation

Basal temperature readings are one of the methods for determining the onset of ovulation. But one measurement will not be enough for you, since each woman will have her own indicators:

• In order for the information to be reliable, you need to make a graph of basal temperature for the last three months
• You need to measure your temperature every day at the same time (read the next section for how to measure your basal temperature correctly)
• After 3 months, make a chart from the first day of the cycle to the last for each month
• During the first phase of the cycle, the basal temperature will be below 37 C
• Then you will see a decrease of several degrees (you may not notice this short period)
• After which there will be a sharp jump
• This will be a signal about the onset of ovulation
• This temperature is elevated and will remain until the onset of the next cycle or will increase during pregnancy.

When the system may fail:

• Woman taking hormonal drugs
• Woman taking other strong medications
• The woman drank alcohol
• Disorders in the body: failure of the hormonal system, women's problems
• The rules for measuring basal temperature were violated (read more about them in the next section of this article)
• Climate change

IMPORTANT: If in any month the temperature does not rise above 37 C, do not worry. This can happen 1-2 times a year. This is called the anovulatory cycle, i.e. cycle without ovulation

Signals to see a doctor:

• Anovulatory cycle occurred more than twice
• Basal temperature rises only towards the end of the cycle, and not during the expected period of ovulation
• The temperature rises and falls throughout the cycle
• If after the onset of menstruation the temperature has not returned to its lower levels, but continues to remain high

IMPORTANT: All information provided will be valid only if the basal temperature is measured correctly (read more below)

Measuring basal temperature to determine ovulation

In order for temperature measurement to be practical, you must comply clearly and strictly rules for measuring temperature:

• Take measurements rectally
• Take your temperature early in the morning while lying in bed. The best time is 7 am
• Use a mercury thermometer
• 5 hours before the measurement you should sleep peacefully
• Place the thermometer next to you so as not to make any body movements. You shouldn’t even shake off the thermometer, prepare it in advance
• Take the measurement for 5-10 minutes
• Take out the thermometer, holding it by its tip. Otherwise you may affect the temperature
• If you make a schedule, then measurements should be carried out at the same time, plus or minus a maximum of 30 minutes

Pain before ovulation

Pain before ovulation can be:
