i really need your help on this one because im young and a child is not what i want, and im so scared that i can't sleep..

Me and my boyfriend didn't have sex for 2 months, so it was a heat of the moment situation, but I take my birth control everyday around the same time, i think i've only been 1 hour off, but that was in the last pack. Sooo, basically we had sex on my period while on the placebo pill, which i took on time..am i pregnant..that was last week, and im waiting on my period to come on, but i don't want it to be too late, idk how this goes, i just don't want to be prego, that's why i'm on the pill....FYI we had sex on the first day of my period, when it just came on :-(

HELP!!!

REPLY SOON pleeeeeease?
