The normal duration of menstruation is 3-7 days. If the period does not clear on the 9th day, it suggests the presence of abnormalities. There are more causes, such as when there is endocrine hormone imbalance, when there are fibroids, endometrial hyperplasia, endometrial polyps, cervical canal polyps, human papilloma virus, including the presence of bilateral adnexal masses, which can cause menstrual dripping. In such a case, go to the hospital to register for gynecological ultrasound to determine whether there are any abnormalities in the uterus and bilateral adnexa. You can take oral anti-inflammatory drugs and hemostatic drugs, and if necessary, check the hormone level to determine whether there is any abnormality in the hormone level. Depending on the case, you can take short-acting oral contraceptives, such as Ursine, Ursine, and Daing-35, for 3 months to regulate your menstrual cycle. Some women are very reluctant to take short-acting oral contraceptives when they hear about them, because they will not only provide contraception, but also regulate the endometrium and menstruation, so at this time, if you want to return to normal conditions, you can take them orally in moderation, without affecting your health.
