How long till birth control stays in your system?

Question

I was taking birth control for about 7 month and stopped about a month and a half ago. I am trying to convince, how long does it take for the birth control to clear my system. Does it matter? Help

Answer

It depends on the type of birth control. The pill and patch are only in your system for afew days after stopping. With the iud (mirena), the hormones stay in the lining of your uterus till you have your next period but can stay in your body as a whole for afew months after. Depo stays in your system for up to 2 years after your last injection and with Implanon it can take up to a year for the hormones to be out of your system. It also depends on the person, for some it's longer and others it's not as long.
