If the drug abortion is not clean, it is recommended to do the following: 1. If the residual tissue is relatively small and does not cause the corresponding clinical symptoms, you can take progesterone orally on the 20th day after the drug abortion, and use the drug for 7 days continuously. 3-7 days after stopping the drug will come to menstruation, and the majority of the residual tissue will be discharged outside the vagina with menstruation, playing the role of drug scraping. 2. If the residual tissue is not cleared in time, the residual tissue is relatively large, which will cause irregular bleeding between the marginal uterine wall and cause a higher possibility of infection. In addition, there is also a risk of heavy bleeding that may affect the patient’s physical and mental health.
