Many women wonder about the difference between Plan B and Plan C. The FDA classifies them separately. They are used at different times and are chemically different. Your reproductive choices can affect you greatly.  Care Pregnancy Clinic provides accurate information and no-cost medical consultation. 

Plan B 

Plan B, also known as the “morning after pill,” is classified as an emergency contraceptive intended for use up to 72 hours after having unprotected sex or realizing that a different birth control method may have failed. 

It is composed of a drug called Levonorgestrel, a synthetic steroid that “blunts the… hormone surge that occurs during the pre-ovulation stage.” It prevents your body from releasing an egg and/or limits the egg’s viability and, therefore, reduces the possibility of a pregnancy.  Plan B is essentially a 50X dose of the contraceptive pill.  As with all drugs, Plan B comes with risks and side effects.  Talk to a  Care Pregnancy Clinic nurse today!

Plan C 

Plan C, also known as the abortion pill, will end an existing pregnancy up to ten weeks in gestation. The FDA does not approve Plan C for use after ten weeks of pregnancy, which is why determining gestational age is very important. For you health and safety, Care Pregnancy Clinic offers no-cost diagnostic screenings.

Plan C is illegal in some states because it is classified as an abortifacient. The FDA does not recommend buying Plan C online because many online sites bypass medical and ethical safeguards designed to protect you.  

The chemical makeup of Plan C is a drug called mifepristone, which is a “selective antagonist of progesterone,” meaning that it cuts off the supply of progesterone to the baby. Therefore, the effects of mifepristone may be reversed by receiving prescription progesterone. If you have started a chemical abortion and would like to reverse course, you can ask for an Abortion Pill Reversal by calling Care Pregnancy Clinic OR by contacting abortiopillreversal.com (1-877-558-0333).
