Women of childbearing age usually need to take contraceptive measures during sexual intercourse. If they do not pay attention to contraception, accidental pregnancy and abortion will cause great harm to women's health. There are many contraceptive methods in daily life. Safe period contraception is a very common contraceptive method. It is said that safe period contraception, but many people do not calculate the safe period in normal times. How to calculate the safe period of contraception?

How to calculate the safe period for contraception?

1. Under normal circumstances, women have menstruation once a month. During a woman's menstrual cycle, there is an ovulation period and a safe period. Women usually ovulate 14 days before their next menstrual period. The egg can generally survive for one or two days, and the dangerous period is before and after ovulation.

2. Male sperm can survive for two or three days after entering the female body. Having sex during the female's ovulation period is most likely to make the woman pregnant. In order to avoid pregnancy, the five days before and four days after a woman's ovulation should be listed as the dangerous period. If you do not want to get pregnant, you should avoid sexual intercourse or use other contraceptive methods during this period.

3. During a woman's menstrual cycle, except for the dangerous period introduced above, the rest of the time is the safe period.

Although there are safe periods and dangerous periods in the female menstrual cycle, it is not absolute. Using this method for contraception has a high chance of failure. Therefore, women are advised to adopt other contraceptive methods with higher success rates.

Is the safe period really safe?

1. Women's ovulation is often easily affected by some reasons, which may lead to premature ovulation. This makes the safety factor after ovulation higher than before ovulation. It is extremely rare for a woman's ovaries to produce two eggs in one menstrual cycle. If an egg has already been released in this cycle, it will usually not be released a second time. Therefore, the period after ovulation is relatively safe.

2. The safe period only means that the chance of pregnancy is lower, not that you will not get pregnant at all. It is very easy to fail when using methods of avoiding a woman's ovulation period to prevent pregnancy, and this method is not as safe as people think. Because there are many factors that affect female ovulation, such as mood, climate, physical condition, etc.

Not only is it difficult to grasp the ovulation time of women, the survival time of men's sperm also varies. Usually it survives two to three days, and some can survive four or five days, which can easily lead to failure of safe period contraception.
