No, the abortion pill and the emergency pill (often called Plan B or the “morning-after pill”) are entirely different.
A simple way to remember the difference is: the emergency pill prevents a pregnancy from starting, while the abortion pill ends an existing pregnancy.

How They Work
-
Emergency Contraception (Plan B/Ella): These pills use hormones to temporarily pause your cycle. If sperm is present but the egg hasn’t been released yet, the sperm has nothing to fertilize. If an egg has already been fertilized and implanted, these pills will have no effect.
-
The Abortion Pill: This is a two-step medical process. The first medication (mifepristone) blocks progesterone, the hormone needed to maintain a pregnancy. The second medication (misoprostol) causes cramping and bleeding to empty the uterus.
Which One Do You Need?
-
If you had unprotected sex recently (within the last few days) and have not had a positive pregnancy test, you should look for emergency contraception at a pharmacy.
-
If you have missed a period and have a positive pregnancy test, emergency contraception will not work. You would need to discuss abortion pill services with a licensed provider.
