If you don’t want to be clean, if the blood HCG is not high, you can take progesterone orally, in order to achieve the purpose of medicinal cleansing, the specific need to follow the doctor’s instructions. The purpose is that when you stop taking progesterone for about 10 days, the endometrium loses the support of exogenous progesterone and tends to have withdrawal bleeding, and the residual tissues will be discharged along with the withdrawal bleeding. If the residual tissue is not expelled by oral progesterone, the uterus must be cleared. If the uterus is not cleared in time, various types of uterine infections may occur, such as cervicitis, endometritis, salpingitis, pelvic peritonitis and other diseases. Therefore, it is recommended that patients who are unable to have a clean abortion should consult a doctor in time and follow the doctor’s instructions to choose the appropriate method of purging the uterus.
