Hi, Please note that even unwanted 72 tablet itself can delay your period for a week or so. Did you do the pregnancy test after missing the period or you took the mifepristone without taking a pregnancy test. If so first do the pregnancy test. If it is negative the problem is solved. Wait for the period to come. 2-5% of them abort following mifepristone alone. If you don t abort take misoprostol 400 micrograms orally 48 hours later. Usually You will start bleeding and abort within 24 hours. The bleeding is heavy in the first 2-4 hours. Light bleeding can continue up to 2 weeks sometimes. If you soak 2 pads in one hour for more than 2 hours or have bleeding for more than 2 weeks you should see the doctor. Take Injection Anti D if you are Rh negative. I hope I have answered to your satisfaction.
