If, for some reason, you take the Mifepristone and then do not take the Misoprostol part of the medical abortion regimen, you can have one of three outcomes:
- You might experience a complete abortion without ever taking Misoprostol.
- You might experience a missed abortion, which means that the fetus is no longer viable, but the products of pregnancy (blood, tissue) do not leave your body. This has to be treated with a vacuum aspiration in hospital.
- Your pregnancy might continue. If you decide you want to keep the pregnancy at this point, it is unlikely that Mifepristone will cause fetal malformations.
Please be aware that there is no evidence that taking Progesterone after Mifepristone can reverse the effects of Mifepristone.
