Common knowledge about women's safe period self-test

When women do not want to get pregnant, they should understand their safe period and dangerous period so that they can use contraception correctly. Many women do not know what their safe period is. Therefore, when women self-test their safe period, they need to understand the common sense of safe period so that the self-test can proceed smoothly. The following is a detailed introduction.

Common knowledge about women's safe period self-test:

1. What is the safe period?

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. From the perspective of contraception, each menstrual cycle of a woman can be divided into the menstrual period, ovulation period and safe period.

Generally speaking, the ovaries of women of normal childbearing age release only one egg per month. The egg can survive for 1 to 2 days after being released, and the sperm can survive in the female reproductive tract for 2-3 days. The fertilization ability is mostly within 24 hours after ovulation. After 2-3 days, the sperm loses the ability to combine with the egg. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may get pregnant. This period is called the fertile period or the dangerous period. A woman's ovulation date is generally about 14 days before the next menstrual period. To be on the safe side, we call the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days, the ovulation period. The rest of the time except the menstrual period is called the safe period.

2. How to self-test during the safe period

The safe period is divided into the safe period before ovulation and the safe period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation. From the first day after the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. The safe period after ovulation is safer than the safe period before ovulation. This is because some women sometimes affected by environmental changes and mood swings affect the advance of the ovulation, so before the safe period ovulation will be shortened, but did not know their own, so before the safety period ovulation is not safe. The opportunity that the ovary has row two eggs in a menstrual cycle is very rare, that is, after ovulation to the next menstrual cramps before this period of time usually won't happen again the second time of ovulation, so the safety period after ovulation is relatively safe.

A woman's ovulation date is generally about 14 days before the next menstrual period. The specific method is as follows: 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 the ovulation day are called the ovulation period. 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. There is no need to use any contraceptive drugs or tools during sexual intercourse during the safe period.

After understanding the common sense of women's safe period self-testing, women should pay attention to these situations when doing self-testing. Moreover, during the self-testing process, if the menstrual cycle is unstable, they can also proceed according to last month. This way, the safe period self-testing will be easier. There will be changes in the safe period of women every month, which women should pay attention to.
