How Long does Birth Control Stay in Your System?

That depends on the type of birth control you are using. The birth control pill can stay in your system for a month after you stop taking it where as depo can stay in your system for several months. It is important to remember that even though it may still be in your system it might not be nearly as affective as it is if you are taking it. So if you stop taking birth control then don’t have unprotected sex unless you are trying to get pregnant.
