How to calculate the heating period_When is the heating period for women

With the positive response to my country's two-child policy. Many people want a second child, but at the same time, for some older women, childbirth can be a very scary and meaningful thing. As women get older, the chances of getting pregnant become very small, and the risk factor is also very high, so those who want a second child do not want to have one. Parents must pay attention to their health.

1. Ovulation period calculation method

Ovulation refers to the period when a normal woman of childbearing age releases a mature egg every month. If a woman has a normal menstrual cycle, she will only have one ovulation period each month and the ovulation period has a certain regularity.

Normal women of childbearing age have menstruation once a month. The period from the beginning of this menstruation to the first day of the next menstruation is called a menstrual cycle. For example, from the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, ovulation period and safe period. [1]

A woman's ovulation date is generally about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days, waiting for fertilization; the male's sperm can maintain its fertilization ability in the female's reproductive tract for 2-3 days, so it is easy to get pregnant through sexual intercourse a few days before and after the egg is released. To be on the safe side, the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days are called the ovulation period. Because it is easy to get pregnant through sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period. Generally, arranging sexual intercourse during the ovulation period can increase the pregnancy rate.

The ovulation calculation method aims to provide services for women's health. It is generally divided into the estimation method, cervical mucus method, basal body temperature measurement method, self-test with ovulation test strips, spotting observation method, B-ultrasound monitoring method, and nipple tenderness method.

2. Principle of calculation of safe period

A woman's ovulation date is generally about 14 days before the next menstrual period. Starting from the first day of the next menstrual period, count down 14 days or subtract 14 days to get the ovulation day. The ovulation day and the 5 days before and 4 days after it are called the ovulation day. For example, a woman's menstrual cycle is 28 days, and the first day of this menstruation is December 2nd. Then the next menstruation will be on December 30th (December 2nd plus 28 days). Subtract 14 days from December 30th, and December 16th is the ovulation day. The ovulation day and the 5 days before and 4 days after it, that is, December 11-20, is the ovulation period. Except for the menstrual period and ovulation period, the rest of the time is the safe period. Theoretically, you will not get pregnant if you have sex during the safe period, and there is no need to take any contraceptive measures. However, if there is an abnormality in the female body, such as early ovulation or two ovulations, then the female may get pregnant. This phenomenon is very rare.
