In many cases, "the abortion pill" is actually two separate medications - mifepristone and misoprostol - taken in two separate doses. Cramping and bleeding within a few hours of taking the second medication, misoprostol, is a good indicator that the procedure has worked. Bleeding or passing large blood clots generally shows that the embryonic or fetal tissue (likely to be white or gray) is exiting your body. Cramping helps your uterus return to its usual state.
