What is the cause of bleeding after having sex right after menstruation?

Generally speaking, normal and harmonious sexual life is not likely to cause vaginal bleeding in women. If bleeding occurs during intercourse, this may be a sign of some pathological condition, and female friends should pay attention to it. So, what does it mean when bleeding occurs right after the menstrual period? Vaginal bleeding after intercourse is more common in the following situations:

1. Caused by uterine wound injury: When a woman's menstruation just ends, there are still some ruptured blood vessels and glands in the uterine wound, the small blood vessels continue to bleed, and the new uterine wall has just begun to grow, which means that it has not yet been covered by epithelial cells. Although the wound had stopped bleeding at this time, it had not been completely reconstructed and repaired. Once sexual intercourse is carried out at this time, the mechanical stimulation will damage the wounds that have not been completely repaired, resulting in bleeding.

2. Caused by vaginal injury: Bleeding during sexual intercourse, heavy bleeding, and long-term bleeding should be considered as the possibility of vaginal laceration. Vaginal lacerations often occur during non-consensual sexual intercourse or extremely rough sexual methods, and can also be seen in some vaginal deformities.

3. Inflammation of the reproductive system: Inflammation of the reproductive system such as cervicitis, vaginitis, endometritis, etc. are all common causes of vaginal bleeding after sexual intercourse.

4. Tumor-induced bleeding: Bleeding during sexual intercourse is one of the risk signals of cervical cancer and the only reliable symptom for early detection of cervical cancer. Uterine cancer bleeding is not much, it is red, or it may be manifested as blood in the secretions. It is because the cervical tissue material becomes brittle after the disease. Once the cervix is ​​hit directly, the tissue will be damaged and bleed.
