You can have intercourse two days after your menstrual period is cleared, and there is usually no residual blood in the uterus and vagina, so it is safer to have intercourse at this time, but if you don’t have fertility requirements, you should do effective contraception at this time to avoid unwanted pregnancy. If you have fertility requirements, you should keep intercourse every other day, so that you will not delay the pregnancy. We must usually pay attention to the hygiene of the vulva and sexual life, relax, do not strain and stay up late, eat lightly and pay attention to exercise. Women’s menstruation may be abnormal due to strain, staying up late, mental stress and bad mood, so it is important to change these bad lifestyles.
