I just got my second shot for birth control, do i have to wait a week again to have unprotected sex?
If you got your second shot on time, it will be effective right away, so there’s no need to wait to have unprotected sex. You only have to wait the week after your first birth control shot. As long as you get your shots about every 12 weeks, you’ll be continuously protected.
If you were two or more weeks late getting your last shot, it’s a good idea to wait to have sex or use a backup method like a condom for the first week.
