How Plan B Works

It’s important to feel informed and in control when it comes to your sexual health and preventing pregnancy.

So let’s start with the facts. Plan B is safe and effective emergency contraception. It is not an abortion pill and will not harm an existing pregnancy.

What you should know about Plan B:

A backup plan you can count on after unprotected sex

Emergency contraception that works by temporarily delaying ovulation

It won’t impact your ability to get pregnant later on

How does Plan B fit into your birth control regimen?

Birth control (or contraception) is any method, medicine, or device used to prevent a pregnancy before it starts. There are many different types of birth control. Some work better than others at preventing pregnancy and no method is 100% effective. But your chances of getting pregnant are lower if you use a more effective method.

If you find that you are using Plan B frequently, talk to your doctor about finding a primary birth control method (a “plan A” method) that is right for you.

Keep in mind:

Plan B won’t interfere with your regular birth control methods or make them any less effective. So, you can continue your regular birth control right away—or start one, if you don’t have a regular method.
