I am on birth control and i didn't plan on having sex, I am horrified mortified and scared to death to get pregnant. anyways. I am on the third pill on the last row, the placebo pills, i'm lightly bleeding, an it had a lil brown in it but. . I was wondering could I/should I take one-two pills from the new packet to be safe? I had sex the other night and he pulled out but i'm horrorified I can't afford plan B an the hospital would be able to get me script in time
