Starting from the time you take the second pill, it usually takes up to six hours for the abortion to be completed, Torres says. So the whole process should be about a few days, during which time you may expel big blood clots or tissue as the pregnancy aborts, Renah Abortion Clinic says. It’s good to rest while all this is happening, if possible. “Most women prefer to stay at home for the first few hours after taking the second set of medicine, so we’ll often talk with them about their schedules to figure out a good time,” Renah says. And after the abortion, you may still experience bleeding for up to four weeks.
