Abortion pills are usually in two doses. The first dose of the abortion pill regimen consists of a drug that works by blocking the hormone progesterone, which normally stops uterine contractions keeping the embryo implanted. The second pill, taken one or two days later, is a hormone that induces labor and softens and dilates the cervix, causing the uterine lining to shed and the embryo to detach and exit the uterus. Women can expect uncomfortable cramps and bleeding, so it’s best to rest at home for one to two days. Are the abortion pills which interfere with the normal body functioning safe ?
