It is generally recommended that you can have intercourse 3 days after your menstrual period has cleared. Because the uterine opening is not yet fully restored when the menstruation has just ended or not completely ended, the secretion increases, at this time coitus is prone to infection, not only will hurt the uterus, but also cause gynecological inflammation. If you have intercourse just after the end of menstruation, it is easy to take the menstrual blood left in the uterine cavity out of the body, which will lead to the return of menstruation, the increase in menstrual flow and other problems, affecting the normal menstruation. And at this time, it is also easy to bring all kinds of bacteria into the uterine cavity, thus breeding some gynecological inflammation, such as vaginitis, endometritis, cervicitis and so on. And three days after the menstrual period, women’s bodies have usually been basically recovered, the cervical opening has been closed, the blood has been discharged, the lining has been completely repaired, coitus usually does not have adverse effects. Therefore, it is recommended to have intercourse three days after menstruation, when the cervical opening is closed and the uterine lining is fully repaired, which can reduce the risk of gynecological diseases; if there is prolonged menstruation, increased menstrual flow or abdominal pain and other discomforts, you should consult a doctor in time, and active treatment. In addition, it should be noted that at any stage of the menstrual cycle, it is necessary to take safe and effective contraceptive measures to prevent unwanted pregnancies from causing harm to the body.
