How many days after menstruation can I have sex without getting pregnant?

Many people, especially the younger generation, have a normal sex life, but they do not understand sexual hygiene and precautions in sexual life. Although many people know that you should not have sex during menstruation, they do not understand the specific reasons. Moreover, for newlyweds, many people will have sex just after the woman's menstruation ends. Some women are also worried about getting pregnant. If you don’t know anything about this, you can take a look!

You cannot have sex during menstruation for three reasons:

1. The cervix opens during menstruation. If you have sex during menstruation, it will cause an increase in menstrual volume and a prolonged menstrual period.

2. It will cause kidney deficiency and back pain on rainy days. The "Stone Chamber Secret Records" says: "If the kidney water (including Gui water) is deficient, the uterus will dry up, and the seedlings will also wither without the moisture of rain and dew."

3. Traditional Chinese medicine also believes that having sex during menstruation will cause sperm to enter the blood, which can also make women infertile. The author Nan Fang believes that the three points emphasized by traditional Chinese medicine are sufficient to answer the question "Can I have sex during menstruation?"

How many days after menstruation can I have sex?

Menstruation nourishes the endometrium and keeps the blood sea filled. You have to wait three days and nights after menstruation before having sex, otherwise there will be qi stagnation, blood stasis, phlegm and dampness, and black blood clots may appear during the next menstruation.

Friends who want to use contraception should also know that women generally ovulate 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 vitality for 2-3 days in the female's reproductive tract, so it is easy to get pregnant by having sexual intercourse a few days before and after the egg is released.

After reading the above introduction by the editor, I wonder if you have a new understanding of having sex after menstruation? Whether during menstruation or just after menstruation, you should pay attention to body care. The female body is very fragile and needs careful care. At the same time, young people who want to use contraception should also take good contraceptive measures, because long-term use of contraceptives and abortion are more harmful to women.
