Yutin is an emergency contraceptive drug and may cause breakthrough bleeding after oral administration, which ends in 3-7 days. However, if the continuous amount is very large, similar to the amount on the 3rd or 2nd day of menstruation, and at the same time has exceeded 7 days, then oral anti-inflammatory and hemostatic drugs are needed to stop the bleeding. It is recommended to go to the hospital to register with the gynecologist for an ultrasound examination to determine the thickness of the endometrium. Oral anti-inflammatory drugs such as cephalosporin or amoxicillin can be taken, and oral hemostatic drugs such as Yunnan Baiyao capsule, Baogong hemostatic granules, and Gonghening capsule can be taken for 5 days according to the instructions to stop the bleeding during the oral period. Also, emergency contraceptives can cause menstrual disorders for a long time. If the disorder exists for a long time, endocrine hormones can be checked to rule out hormonal abnormalities. Cycle regulation can be carried out to avoid prolonged disorders affecting ovulation.
