How to count the day of ovulation. How to calculate the first day of ovulation

The female organism is a very complex and perfect system. And only lovely ladies are awarded a unique ability to reproduce. For this function, the reproductive organs are responsible, and the main role is played by the ovaries. It is in them that the egg is formed and grows, which is fertilized. A primary embryo is formed from it.

Ideally, every month a healthy cell emerges from the ovary, from which all the cells of the new organism are formed. But, unfortunately, there are many factors in life that affect this complex process. Therefore, there are many ways that help to figure out how to calculate the day of ovulation.

Accuracy in counting

Each woman, carrying out difficult calculations, pursues completely different goals. Someone dreams of replenishing the family, while others try to calculate the days, which can not be conceived. In fact, the "theory" works for both sides. But scientists say that ovulation is a natural process that is difficult to call permanent and unchanged. Even in a healthy lady, this phenomenon does not happen every month! Full cycles in the year is about 9-10. In addition, it is sometimes difficult to calculate the exact date of maturation of the egg due to an irregular menstrual cycle. How to count the day of ovulation? It is necessary to take into account the influence of many factors:

• Hormonal changes;
• Cycle length;
• Well-being of a woman;
• external factors.

Only an integrated approach will allow to establish with greater accuracy the time of the release of the ovum from the ovary.

Reliable contraception

Just want to note that if you intend to use the data on ovulation to prevent pregnancy, these calculations are not always relevant! A mature egg does not last very long, about 24-48 hours, but a male sperm cell can remain "mobile" for up to 5 days. Therefore, the sexual act before and after ovulation for 5 days is considered "unprotected" from fertilization.

And there are situations when the ovary can immediately ripen 2 cells and it happens, for example, 2 times a month. Be extremely careful, using these calculations. It is worth to familiarize in detail with all the existing methods of determining ovulation, which can be used in practice.

Calendar method

This way to track the ripening cell is quite simple and widely used. In order to use it, you need to accurately track the menstrual cycle for six months. It is from the actual information about the duration of the cycle that the question will depend on how to accurately calculate the day of ovulation. Be sure to record the dates of bleeding, their duration.

Luteal phase, as a rule, lasts for women approximately 14 days. And despite the fact that the number of days in the cycle can vary, ovulation occurs 14 days before the onset of the next menstruation. That is, a simple calculation should be made: 28-14 = 14, where 28 is the estimated duration of menstruation, 14 is the luteal phase, 14 is the day of expected ovulation (count from the day of the next bleeding).

This method is perfect for women with an "established" regular cycle. However, pay attention to your shortest menstruation. To determine from which day the favorable period for conception comes, subtract from the "small" cycle 18. But the last "suitable" day can be learned by subtracting 11 from a given number. Ovulation occurs on the day, which you calculate using continuous observation of the cycle.

Temperature option

Doctors offer another accurate method for tracking the ripe cell. By measuring the basal temperature, one can see the change in the general background in the body. How to calculate the day of ovulation with a thermometer?

The fact is that in the first phase of the cycle, estrogen predominates in women, and in the second - progesterone. These changes can be easily tracked by measuring the temperature in the anus. Do this every morning, without getting out of bed.

However, this method requires regular recording and scheduling. Every day you need to record the temperature. As a rule, its index in the first phase is 36.5-37 ° C, but after the onset of ovulation it sharply "jumps" from 37 to 37.5 ° C. It is the day in which the changes are observed, and is the day of release of the egg from the follicle.

Natural selection

You can try to determine the "suitable" day, based on the reaction of the body. During the exit of the cell from the ovary, the hormonal background changes, a thicker and more viscous grease appears. It is she who helps to move the sperm into the uterus. Write down every day changes in cervical mucus. Slide your finger along the vaginal wall - and if you observe an elastic viscous and sticky grease, this may indicate that ovulation occurs on the day of the cycle that corresponds to the start of the luteal phase. To make sure the information is up to date, watch for secretions for several months.

Special tests

If it is unacceptable for you to keep records or to measure rectal temperature every day, you can take tests for ovulation. They are special strips or cassettes, on which a sensitive reagent is applied. The woman should determine the approximate period of maturation of the cell according to the calendar and start using the test 3-5 days before ovulation. This method works by increasing progesterone in the urine. It is necessary to conduct research twice a day, at the same time. This will help not miss the right moment.

The first day of ovulation will be reflected in the test field with two bright red stripes. However, if you use tests, you need to consider some features:

1. The best time for research is from 10 am to 20 pm.
2. Morning urine is not used.
3. Do not drink a lot 1-3 hours before the test.
4. The result in the control field can be evaluated for 30 minutes.

How to calculate the day of ovulation, based on the findings, in order for conception to occur or for contraception? In fact, you can approach any of the methods outlined above. But remember: no result can be considered 100% correct information. After all, each organism is individual, and factors that affect the level of hormones are enough. If you do not want to miss an "important" day, contact a doctor who can prescribe ultrasound for the growth of the follicle and the onset of ovulation.
