The female body is very interesting. Within one month, the body of the weaker sex is undergoing the strongest changes. Many women try to calculate on which day of the cycle ovulation occurs. This is what the article will be about. You will learn when ovulation occurs and how to calculate it. You can also get acquainted with the peculiarity of the frequency of this process.

On which day of the cycle does ovulation occur? Periodicity and methods for determining ovulation

On which day of the cycle does ovulation occur? Ask a specialist

If you ask this question to your doctor, you probably will not get a definite answer. Doctors say that the egg from the dominant follicle occurs about 10-16 days before the next menstruation. This indicates that the second phase of the cycle always has the same length. It is worth noting that if this period for a representative lasts 12 days, then in subsequent cycles it will not increase to 16, but will not decrease to 10. The second phase always remains at the same length.

From the above, it can be concluded that ovulation with an irregular or stable cycle takes about two weeks. In this case, the normal cycle length can be from 21 to 35 days. If a woman’s period is more or less than that, then we are talking about a pathology that requires medical intervention.

Long cycle

On what day of the cycle does ovulation occur, if the duration of the period from one menstruation to another is 34-36 days for a woman? Doctors call such a length of time a long cycle. However, it is an absolute norm, subject to regularity.

If we take into account that the second phase of a woman lasts 10–16 days, then the follicle in a long cycle is broken for about 18–26 days. For more accurate data, it is worth tracking ovulation in ways that will be described later in the article.

Average woman

When does ovulation occur, if the female cycle lasts four weeks? It is about this period that doctors say, calling it the average. Indeed, the majority of the representatives of the weaker sex cycle lasts 28 days.

Ovulation in this case occurs from 12 to 16 days. Adding to this value the average duration of the second phase, we obtain the above cycle length. It should be noted that the average women have anovulatory cycles during their lifetimes. About them will be discussed in more detail below.

Short menstrual cycle

On which day of the cycle does ovulation occur in those women who have a short period? With a cycle duration of three weeks, the dominant follicle breaks very early. This usually happens right after the end of menstruation, on the sixth or eighth day.

It is worth noting that such an early release of the egg is the absolute norm. However, most women believe that the gametes are not fully mature. This opinion is erroneous. Ovulation is performed only when the cell of the woman is fully mature and ready for fertilization.

Frequency of ovulation in women

As you already know, the menstrual cycle can be of three different types. At the same time, in the course of life this duration in women may vary. So, often drastic changes occur after childbirth or hormonal diseases. It is worth noting that currently there are special hormone-containing agents that allow you to adjust the duration of the cycle and change it somewhat. However, they should be appointed exclusively by a doctor.

Doctors say that even an absolutely healthy woman in a year can have several cycles in which the ovaries “sleep”. In other words, during these periods the follicles do not mature, and the egg cell does not leave the reproductive organs of the weaker sex. In this case, it does not matter at all what the duration of the cycle is. However, statistics suggest that women with a short cycle are more likely to encounter the term “anovulation.”

How to calculate the ovulation cycle?

Currently, there are many ways to track and calculate the frequency of ovulation. Some methods a woman can quite simply apply herself. These include temperature measurement, the use of test systems, control of secretions and the position of the cervix.

Other ways to calculate the ovulation cycle include medical intervention and the use of special equipment. These include ultrasound diagnostics, laboratory studies of hormone levels, and so on. Consider the basic methods for determining ovulation.


The ovulation test reviews are rather inconsistent. This method is very easy to use. You only need to buy the system in the pharmacy chain or in the supermarket. After that, on a certain day you need to start the study. The package is usually offered from five strips. Before using the ovulation test, the instructions should be carefully studied. Pay attention to the fact that the study is recommended to start not in the morning, but in the afternoon. It is during this period that the maximum hormone production occurs. How to apply the test for ovulation?

The instruction states that you should refrain from urinating for two to four hours. During this period, you should not drink large amounts of liquids. Collect urine in a clean and dry container. Lower the test to the specified level. After that, wait five minutes and evaluate the result. A positive indicator can be considered when the test strip showed up clearly and became brighter than the control one. If the ovulation test was used correctly, the testimonials and instructions indicate that the follicle will break in about 12-24 hours.

Temperature charting

The ovum lives only a few hours after ovulation. That is why it is so important not to miss the crucial moment. You can determine ovulation with great accuracy using a temperature graph. To do this you will need a thermometer and a little patience.

Regularly measure the level of temperature in the rectum. Please note that the study should be conducted every morning at the same time period. If there is a deviation of half an hour, then the data will be inaccurate. Enter the values ​​in a notebook and make a graph of them. You will clearly see the location of the curve line. Thus, in the first phase of the cycle, low body temperature is maintained under the action of estrogens. Usually it is in the range of 35.9 to 36.6 degrees. Around the middle of the cycle, on those days when ovulation is to occur, a slight depression occurs. It depends on the production of luteinizing hormone, which contributes to the rupture of the follicle. So, on this day the body temperature is reduced by several divisions. When maintaining the schedule is quite clearly noticeable. It is on such a day that ovulation should take place. The very next morning you will see great values ​​on the thermometer. Usually they are in the range of 36.8 to 37.2 degrees. These numbers indicate that ovulation has occurred, and the hormone progesterone has been activated.

Ultrasound monitoring

One of the most effective ways to calculate the day of ovulation is ultrasound tracking. Doctors call this manipulation folliculometry. So, during it is made from one to four studies per cycle. In this case, the doctor independently calculates and assigns suitable dates for monitoring. It should be noted that folliculometry involves only tracking the state of the ovaries and follicles. During diagnosis, the doctor does not pay attention to the condition of the uterus and fallopian tubes. When the follicle reaches the size of two centimeters, an important hour will soon come.

How much ovulation will occur after the examination? The time interval from the study to the release of the egg can be from two to twelve hours. If you are planning a child, then it is during this period that it is best to have sexual contact. Experienced specialists after the first folliculometry can roughly say about the day of ovulation. However, for a more accurate calculation, it is necessary not to miss all appointments.

Hormonal research

As you already know, the female cycle throughout its length is replaced by some hormones for others. So, in the first half estrogen dominates, then it is replaced by progesterone. At the border of these substances, luteinizing hormone is produced. Also in a small number of women in the body have testosterone and androgen. If you donate blood and conduct its research, you can determine the level of luteinizing hormone. It reaches its maximum a few hours before ovulation.

It is worth noting that this method is quite reliable, but it is used very rarely. All because of the high cost and inconvenience of research. As you can see, test systems for tracking ovulation have a similar operating principle.

Own observations

How to determine the moment when ovulation occurs? For 30 days (throughout the cycle) a woman should monitor the work of her body. However, sometimes one period is not enough. After several months of observation, the representative of the weaker sex will be able to quite accurately determine the length of time when ovulation should occur. The corresponding symptoms will be reported to her. These include the following indicators:

  • vaginal discharge acquire a more fluid consistency and become similar to egg white;
  • increased sexual desire;
  • sense of smell rises and taste preferences change;
  • lower abdomen pulls on one side;
  • the cervix opens and becomes softened.

It must be remembered that in order to track the discharge and condition of the cervix you will have to conduct a vaginal examination yourself. This should be done very carefully. Pre-cut nails briefly and wash hands with anti-bacterial soap. You can also wear sterile medical gloves. It is more convenient to do the study, squatting.

Instead of conclusion

Now you know on which day of the cycle ovulation occurs in one way or another. Remember that the organisms of women have individual characteristics. Do not compare yourself with your friends and acquaintances. For the most accurate tracking of ovulation, use several methods at once. If you can not calculate the date of rupture of the follicle or suggest that this is not happening, you should contact the doctors. The doctor will prescribe a hormonal study that will accurately determine your health condition.

In the absence of ovulation, it can be stimulated with the purpose of subsequent pregnancy. However, preparations for this should be prescribed only by a gynecologist. Independent effects on hormones can lead to serious problems. Be healthy!
