Doctor's answer:

Intercourse during menstruation can easily lead to infections. However, (1) it can cause various inflammations, such as endometritis, fallopian tube inflammation, pelvic inflammatory disease, and even infertility. (2) The uterine contractions caused by intercourse during menstruation may push menstrual blood into the abdominal cavity, increasing the risk of endometriosis. (3) During menstruation, some sperm and other components of semen may enter a woman's bloodstream through small blood vessel tears, stimulating the immune system to form antisperm antibodies and leading to immunological infertility. (4) Various blood-borne infectious diseases can be transmitted. (5) Intercourse during menstruation can cause increased bleeding or prolonged bleeding duration. It is best to avoid this situation as much as possible. If it happens occasionally and there are no other abnormal symptoms, it is not a major issue—just wait and see, and avoid treatment for now. Don't worry. Consider yourself lucky, but frequent occurrence may lead to the problems mentioned above. Pay attention to avoiding this situation as much as possible.
