Recently I have been trying different birth controls because of the extreme side effects some give me. I've finally found one to stick with. I've heard they kick in after 1 week and you should be covered. I had sex on the 7th night I had been taking them.. we also used a condom. I'm all about protection. The condom slipped off.. he hadn't ejacualted yet. I got the morning after pill just in case the birth control hadn't kicked in yet and took it within 11 hours. I have only used the morning after pill one other time.. and I had withdrawal bleeding from it. But this time I am not experiencing that. Just wondering how high you think the possibility of pregnancy is? Since I've been experimenting with birth controls my period hasn't been so regular but my last one was around March 5th so I'm expecting one with the next week or so..
