The Abortion Pill is considered an early abortion method, because it only works during early pregnancy. Under 9 weeks of pregnancy, the uterus is getting ready for the pregnancy by developing a thickened lining inside, called “decidua”. The decidua is similar to the lining that comes out with your period, but a little thicker. This is why the Abortion Pill is said to “bring down your period.”
The Abortion Pill is actually two sets of pills. The first pill, mifepristone, blocks the pregnancy hormones from reaching the uterus, so the tissue lining stops growing and starts to detach from the uterus. The second set of pills, misoprostol, cause the uterus to contract and the cervix to relax and open. This induces your period, or causes an early miscarriage.
