The chances of a clean abortion are relatively high, with a success rate of about 85%-90%, but not all people will be successful after a medical abortion, and there is a possibility of failure. If you have bleeding from the vagina for a period of time after the abortion, you need to have a timely examination to determine your health condition and see if there are any other complications. Mifepristone tablets and misoprostol are used in medical abortions to provide combined treatment to terminate the pregnancy. If you are afraid of failure, it is best to choose the right abortion method for you. Medication abortion is not suitable for everyone and it is best to consult your doctor before aborting.
