If there is blood again a few days after menstruation stops, it is considered that there may be ovulation bleeding, endometritis, luteal insufficiency, cervical lesions or endometrial lesions. 1. Ovulation bleeding: after the patient’s menstruation stops, a small amount of bleeding may occur during the ovulation period, that is, about 14 days before the next menstrual period, due to changes in hormone levels in the body that cause part of the endometrial lining of the uterus to shed, resulting in a small amount of bleeding. 2. Endometritis: when the patient has endometritis, there may also be a few days of bleeding after the menstrual period stops, which needs to be combined with the uterine ultrasound examination, gynecological examination, etc. to determine whether there is a possibility of bleeding after the menstrual period stops. It is necessary to combine with uterine ultrasound and gynecological examination to make a judgment. 3. Luteal insufficiency: Luteal insufficiency is because the luteal function is insufficient after the menstrual period is over, and the endometrium can’t be completely repaired, so the bleeding problem occurs again. 4. Cervical lesions: the above phenomenon may also occur if there is cervicitis, precancerous lesions or cancerous lesions of the cervix. 5. Endometrial lesions: If there are endometrial polyps, submucosal fibroids, pre-cancerous or cancerous lesions of the endometrium, bleeding may also occur a few days after menstruation has stopped. There may be other reasons for bleeding after a few days of menstruation, so it is recommended to consult the gynecology department of a regular hospital to find out the reasons and follow the doctor’s instructions for treatment in time if necessary, so as to avoid delaying the condition.
