Hey guys, i could use some advice. I started a new birth control a few months ago and maybe in December was the only month i took it everyday. February i kind of slacked on taking it, i took it every once in a while. But March i took it pretty much everyday. Well my boyfriend and i had sex a few weeks ago.... he didn't finish... we got interrupted (that's a whole different story). Anyway i was supposed to get my period a few days ago and i haven't got it yet...i don't know if i should be concerned or its just because of me taking my birth control regularly again. Anyone?
