You can have intercourse two days after your period has stopped. If you have intercourse too early, it will easily lead to reflux of menstrual blood and induce endometriosis. The risk of endometriosis due to premature intercourse is increased because the endometrium has not yet healed completely. The menstrual period is a unique period for women and requires special attention to personal care. First of all, it is necessary to strengthen personal hygiene, change sanitary products frequently, keep the intimate area clean, and drink more warm water to promote excretion. Secondly, you should not eat cold food during menstruation, your abdomen and feet should not be cold, bad habits can lead to menstrual cramps, and the poor resistance of the body during menstruation is particularly easy to catch a cold and get sick. Lastly, you should not overwork or exercise during menstruation, as the coagulation function will change during menstruation, and overwork and exercise may prolong the menstruation period and increase the volume of menstruation.
