Based on physiology
The physiology of any woman of childbearing age is constructed in such a way that the chance to become pregnant exists every month. It is called the period of ovulation. At this time, the egg is ready for fertilization, and this period lasts 1-2 days. It coincides with the middle of the menstrual cycle. For example, if a woman has 28 days, ovulation occurs on the 14-16th day. With a 35-day cycle, it is approximately 17 days. Many women want to know exactly when the days of ovulation come, because if the cycle is not stable (one month is 28 days, another is 31 days), then you can make mistakes in calculating them.
In this case, you can use other methods:
- Buy an ovulation test at a pharmacy, carefully read the instructions and if the test is positive, you should (or should not) have sex. Thus, the egg ready for fertilization merges with the spermatozoon and an embryo is formed.
- Measurement of basal temperature. Begin to measure temperature with a thermometer in the mouth or rectum from the first day of the cycle, that is, with the onset of menstruation. The data is entered every day into the schedule. During the onset of ovulation, you will fix a slight increase in temperature. If at the beginning of the cycle it was 36.8, then during the ovulation period the thermometer will show 37-37, 2. This is a signal about the onset of ovulation and a favorable period for conception.
- Changes in well-being. During the period of ovulation, the chest swells a little, the stomach hurts, the vaginal discharge becomes viscous.
- Ultrasound. This method most accurately diagnoses the period of onset of ovulation.
Based on these methods, women can predict the "dangerous" and "safe" days of their cycle.
Can I get pregnant before my period?
Theoretically, most doctors will answer the question "no." After all, if during the ovulation period the egg was not fertilized, she dies and with the flow of blood comes out of the vagina during the period of menstruation. They are complicated by the conditions necessary to attach a fertilized egg. The hormonal background before menstruation is adjusted for a new cycle. That is why it is practically impossible to conceive. But! If a woman's intimate relationships are irregular, then the opportunity to become pregnant before the monthly increases. The fact is that intimate relationships give rise to an unplanned ovulation. That is, the peak of sexual pleasure can lead to an emergency exit of the oocyte, which is then fertilized by the sperm. This happens when a man and a woman were separated for a long time and kept each other faithful. Pregnancy before menstruation can happen even when a woman is constantly protected, not allowing sperm in the vagina. When, after such a long form of protection, unprotected intercourse occurs, then the onset of pregnancy is likely.
Can I get pregnant after a month?
The above examples are typical of the period after the month. That is, theoretically, a woman who has a constant partner and leads a regular sex life, can not become pregnant. After all, at this time the egg is not yet ripe and is not ready for fertilization. But in practice, it happens that very active spermatozoa that fall into the female body immediately after menstruation can be ready for a week to meet the already mature egg. That is, sexual intercourse occurs after menstruation, ovulation on schedule, and a woman becomes pregnant.
And another reason for pregnancy immediately after menstruation may be failures in the female body. After all, in the conditions of our ecology the body does not work like a clock. A healthy woman has a bias and cycles, and periods of ovulation. This means that today it is difficult to call with absolute precision & bdquo; dangerous & rdquo; and & bdquo; safe & rdquo; the days of women.
