Normally, menstruation will clear in 3-7 days. If the period is more than 9 days clinically, it is abnormal uterine bleeding. If it usually clears in 4-5 days and now it is not clear for a week, it may be due to estrogen deficiency and late repair of the endometrium, which may result in unclear menstruation. In this case, you can treat the symptoms, for example, you can take oral hemostatic drugs, like Yunnan Baiyao or Wujia Biochemical Capsules, to promote uterine contraction to reduce bleeding and promote the repair of the endometrium. In addition, if the menstruation does not clear after the medication, it is recommended to go to the hospital for a detailed examination to rule out endometrial lesions, such as endometrial inflammation, endometrial polyps or submucosal fibroids of the uterus.
