The female body is a very complex and perfect system. And only lovely ladies were awarded the unique ability to reproduce offspring. 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, a healthy cell comes out of the ovary every month, from which all the cells of the new organism are formed. But, unfortunately, there are many factors in life that influence this complex process. Therefore, there are many ways that help to figure out how to calculate the day of ovulation.
Counting accuracy
Each woman, conducting complex calculations, has completely different goals. Someone dreams of replenishment in the family, while others try to calculate the days on which it is impossible to conceive. In essence, “theory” works for both sides. But scientists say that ovulation is a natural process that can hardly be called constant and unchanged. Even in a healthy 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 egg maturation due to an 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;
- well-being of a woman;
- external factors.
Only an integrated approach will make it possible to more accurately determine the moment the egg leaves 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 does not live very long, about 24-48 hours, but the male sperm is able to remain “mobile” for up to 5 days. Therefore, sexual 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 right away and this happens, for example, 2 times a month. Be extremely careful when using these calculations. It is worth familiarizing in detail with all existing methods for determining ovulation that can be applied in practice.
Calendar method
This method of tracking a ripening cell is quite simple and widely used. In order to use it, you need to accurately monitor the menstrual cycle for six months. The question of how to accurately calculate the day of ovulation will depend on actual information on the duration of the cycle. Be sure to write down the dates of the onset of bleeding, their duration.
The luteal phase usually lasts about 14 days in women. And despite the fact that the number of days in the cycle can vary, ovulation occurs 14 days before the next menstruation. That is, it is worth a simple calculation: 28 - 14 = 14, where 28 is the estimated duration of menstruation, 14 is the luteal phase, 14 is the day of the supposed ovulation (count from the day the next bleeding occurs).
This method is perfect for ladies with a "well-established" regular cycle. However, pay attention to your shortest menstruation. To determine from which day the favorable period for conception begins, subtract from the "small" cycle 18. But the last "suitable" day can be found by subtracting 11 from this number. Ovulation occurs on the day that you calculate by constantly monitoring the cycle.
Temperature option
Doctors offer another accurate method to track a mature cell. By measuring basal temperature, you can see a 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, but in the second - progesterone. These changes can be easily tracked by taking temperature measurements in the anus. This should be done every morning without getting out of bed.
However, this method requires regular recording and scheduling. Every day you need to record temperature observations. As a rule, its indicator in the first phase is 36.5-37 ° , but after the onset of ovulation it sharply “jumps” from 37 to 37.5 ° . It is the day on which the changes are observed that is the day the egg leaves the follicle.
Natural discharge
You can try to determine the "suitable" day, based on the reaction of the body. During the release of the cell from the ovary, the hormonal background changes, a thicker and more viscous lubricant appears. It is she who helps the sperm advance into the uterus. Record changes in cervical mucus every day. Slide your finger along the wall of the vagina - and if you observe elastic viscous and sticky lubrication, this may indicate that ovulation occurs on the day of the cycle, which corresponds to the beginning of the luteal phase. To verify the relevance of the information, monitor the discharge for several months.
Special tests
If it’s unacceptable for you to record or measure rectal temperature every day, you can use the 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 on the calendar and begin using the test 3-5 days before ovulation. This method “works” due to an increase in urine progesterone. It is necessary to conduct research twice a day, at the same time. This will allow you not to 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:
- The best time to study is from 10am to 8pm.
- Morning urine is not used.
- Do not drink a lot 1-3 hours before the test.
- The result on the control field can be evaluated over 30 minutes.
How to calculate the day of ovulation, based on the data obtained, in order for conception to occur or for contraception? In fact, you can use any of the methods described above. 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 want to not miss the “important” day, consult a doctor who can prescribe an ultrasound scan for follicle growth and the onset of ovulation.
