When and how do you stop using the birth control patch?

When you are using the patch and have your "Week off" period week. You take it off as you normally would and then wait. It can be a few months for your peiod to return but you can get pregnant even before you get your next period. So use protection even if you want to get pregnant (easier for figuring out due date) You may notice "symptoms" of being pregnant as your body gets used to being off the patch. If you get worried test.
