MiMi: A Randomized Trial of Mifepristone and Misoprostol for Treatment of Early Pregnancy Failure

Summary

The purpose of this study is to compare two combinations of drugs (mifepristone and misoprostol versus placebo and misoprostol) used for medical treatment for early pregnancy failure. We will compare the two combinations of medications to see which combination makes miscarriage happen faster. We hypothesize that there will be no difference in time to complete miscarriage between the two groups.
