After the hymen was repaired, we returned home, and we did the postoperative care according to the doctor's instructions. However, vaginal bleeding appeared a few days later. At this time, let's not worry. Only by finding out the cause of bleeding can we make a treatment plan. 1. Unexpected rupture of hymen: There are many reasons for hymen rupture, not only because of sexual life, but also because of strenuous exercise or accidental fall, and the hymen after hymen repair is more fragile. If we just accidentally fall or lift our legs in our daily activities, we may cause the hymen to rupture on our own. 2, menstrual cramps: hymen repair surgery will generally choose to be carried out after a week of clean menstruation. Some women may be close to the next menstrual date in the selection time, so they will enter the physiological period soon after the hymen is repaired, and there will be bleeding in the lower body, but the blood here is only necrotic cells excluded during the physiological period, not because the hymen is broken. This situation can be ignored, but vaginal hygiene should be strengthened.
