I've been on birth control pill for over 10 years and I was traveling and made the mistake of waiting 5 days after I finished my pack to Start the new pack. I had unprotected sex with my boyfriend the first day I started my new pack. He pulled out but I know that's not an effective form of birth control. Should I take the morning after pill? I heard somewhere that you can wait 7 days before you start the new pack but not sure if that's correct. And if I take the morning after pill and continue with my birth control, will the pill still be effective?
