Why does bleeding occur after having sex if the menstrual period is not over?

Menstruation is also called period, and some people call it aunt's period. In short, menstruation is a way to keep women healthy. It can help women's metabolism and expel dirt from the body. Women with normal menstruation tend to look younger than their peers, so menstruation is very important for women. However, in real life, some women have sex with their husbands during their menstruation period, which is really incomprehensible. So, why does bleeding occur after intercourse if the menstrual period is not over?

Bleeding during intercourse right after menstruation may be caused by gynecological diseases. Bleeding during intercourse after menstruation cannot rule out gynecological diseases such as vaginitis, cervical polyps, cervical erosion, early cervical cancer, and submucosal fibroids.

It could also be menstrual blood that has not been completely discharged. Some female friends resume sexual intercourse immediately after the menstruation is over. In fact, at this time there are still broken blood vessels and glandular ducts on the surface of the uterine cavity, and the tiny blood vessels will still bleed. The stimulation of sexual intercourse will cause bleeding. For this case, female friends should pay attention to having sexual intercourse two or three days after menstruation, otherwise it may cause infection and lead to gynecological diseases.

It could also be ovulation bleeding. Women will enter the ovulation period a few days after the menstrual period. Some women will experience ovulation bleeding. During the ovulation period, due to a brief drop in estrogen levels, the endometrium loses hormonal support and some endometrial tissue falls off, causing regular vaginal bleeding, but the amount of bleeding is not much. Some people only have a small amount of brown secretions, which usually lasts for half a day or 2-3 days, and no more than 7 days at most, and may be accompanied by slight back pain. For postmenstrual bleeding caused by this situation, if the symptoms are mild, no treatment is needed, but if the symptoms are obvious and accompanied by other abnormal symptoms, it should be taken seriously and actively treated.
