There are many reasons why menstruation normally ends in 7 days and bleeding continues for 9 days. For example, when there is an endocrine hormone imbalance, the hormonal changes can cause dripping. When there are fibroids, hyperplasia of the endometrium, cysts in the adnexal area, or polyps at the cervical opening, it can also cause dripping menstruation. In some cases, oral medications, such as emergency contraceptives, may cause menstrual flow that does not end after 9 days. In such cases, it is necessary to go to the gynecology department for an ultrasound examination to determine whether there are any abnormalities in the uterus and both adnexa, and a blood test is recommended to determine whether there is any anemia or infection. According to the situation, oral anti-inflammatory and hemostatic drugs should be taken to avoid prolonged bleeding affecting the health of the body.
