So I had unprotected sex about two weeks ago, I am on the patch and I had the sex on the third week of the birth control cycle(I have been on it for three months now) I also took a morning after pill 4 days after having sex, because I was scared and all that jazz..it's been a week since I have been off my patch and I still haven't gotten my period, am I pregnant or paranoid? I've been pregnant once before that's why I'm so worried..
