Vaginal bleeding during ovulation is not a menstrual flow, but a small amount of endometrial peeling and bleeding due to a temporary drop in estrogen levels in the body that cannot support endometrial proliferation, which is a normal physiological phenomenon. This is a normal physiological phenomenon. It usually lasts for about three to five days and the bleeding will stop after the hormone level rises and the lining is repaired. If the bleeding is not heavy and there are no other uncomfortable symptoms, no special treatment is needed except for paying attention to the cleanliness and hygiene of the vulva. If ovulatory bleeding occurs continuously, or if it affects normal conception, you should go to the hospital for ultrasound, sex hormones, gynecological examination and hysteroscopy to rule out luteal insufficiency, submucosal fibroids, endometrial polyps and other diseases.
