A period that has not cleared for 15 days is abnormal uterine bleeding. Generally, the normal menstrual period is 2-7 days. If the menstrual period is not cleared for more than 7 days or more than 7 days, it is pathological and the cause should be actively investigated. If you are of childbearing age, you should rule out that the dribbling is due to pregnancy and that the dribbling is caused by a preterm miscarriage, you should have a blood HCG and ultrasound test to find out if it is due to pregnancy. If it is due to preterm miscarriage, active fertility treatment should be performed if you want to have a baby. If it is not due to pregnancy, a gynecological examination should be performed to understand the condition of the cervix, whether it is caused by cervical polyps or cervical erosion, and an ultrasound examination should be performed to understand the condition of the uterine adnexa and endometrium, whether it is caused by endometrial polyps or submucosal fibroids.
