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

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

Accuracy in counting

Each woman, carrying out complex calculations, pursues completely different goals. Someone dreams of replenishment in the family, while others try to calculate the days on which it is impossible to conceive. Basically, the "theory" works for both sides. But scientists say that ovulation is naturala process that can hardly be called constant and unchanging. Even in a he althy lady, this phenomenon does not occur every month! There are about 9-10 full cycles per year. In addition, it is sometimes difficult to calculate the exact date of maturation of the egg due to the irregular menstrual cycle. How to calculate the day of ovulation? It is necessary to take into account the influence of many factors:

• hormonal changes;
• cycle length;
• women's well-being;
• external factors.

Only an integrated approach will allow us to determine with greater accuracy the moment of release of the egg from the ovary.

Reliable contraception

I want to note right away that if you intend to use ovulation data to prevent pregnancy, these calculations are not always relevant! A mature egg cell lives for a very short time, about 24-48 hours, but the male spermatozoon is able to remain “mobile” for up to 5 days. Therefore, intercourse before and after ovulation for 5 days is considered "unprotected" from fertilization.

And there are situations when 2 cells can ripen in the ovary at once and this happens, for example, 2 times a month. Be extremely careful when using these calculations. It is worth familiarizing yourself in detail with all the existing methods for determining ovulation that can be applied in practice.

Calendar method

This method of tracking a maturing 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 fromup-to-date information on the duration of the cycle will depend on the question of how to accurately calculate the day of ovulation. Be sure to write down the dates of bleeding, their duration.

The luteal phase typically lasts about 14 days for women. And despite the fact that the number of days in the cycle may vary, ovulation occurs 14 days before the next menstruation. That is, it is worth making a simple calculation: 28 - 14 \u003d 14, where 28 is the estimated duration of menstruation, 14 is the luteal phase, 14 is the day of the expected ovulation (calculated from the day the next bleeding occurs).

This method is perfect for ladies with an "established" regular cycle. However, pay attention to your shortest period. To determine from what day the favorable period for conception begins, subtract 18 from the “small” cycle. But the last “suitable” day can be found by subtracting 11 from this number. Ovulation occurs on the day you calculate by monitoring your cycle continuously.

Temperature option

Doctors offer another accurate method for tracking mature cells. By measuring the basal temperature, you 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 in women, estrogen predominates, but in the second - progesterone. These changes can be easily tracked by measuring the temperature in the anus. This should be done every morning without getting out of bed.

However, this methodrequires regular recording and scheduling. Temperature observations should be recorded daily. As a rule, its indicator 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 on which changes are observed that is the day the egg is released from the follicle.

Natural secretions

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 lubricant appears. It is she who helps to move the sperm into the uterus. Record changes in cervical mucus every day. Run your finger along the wall of the vagina - and if you observe an elastic, viscous and sticky lubricant, this may indicate that ovulation occurs on the day of the cycle, which corresponds to the beginning of the luteal phase. To make sure the information is up to date, observe the discharge for several months.

Special tests

If it is not acceptable for you to take notes or measure your rectal temperature every day, you can use ovulation tests. They are special strips or cassettes on which a sensitive reagent is applied. A woman should determine the approximate period of cell maturation 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 is what will allowmiss 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 take into account some features:

1. The best time to explore is from 10 am to 8 pm.
2. Do not use morning urine.
3. Don't drink heavily 1-3 hours before the test.
4. The result on the control field can be evaluated within 30 minutes.

How to calculate the day of ovulation, based on the data obtained, in order to conceive or for contraception? In fact, any of the above methods may work for you. But remember: no result can be considered 100% correct information. After all, each organism is individual, and there are enough factors that affect the level of hormones. If you don't want to miss the "important" day, see your doctor who can schedule an ultrasound to check for follicle growth and ovulation.
