I am supposed to start my period on the 17th. I had unprotected sex on the 24th of Feb and then again on March 5th. both times he didn't finish in me but some ppl say there's still a "chance" cuz of precum. I'm not feeling any symptoms, just nausea and bloating. should I take the plan b pill? I'm just nervous that it's gonna delay my period and then when my period is supposed to come around I'll get extra worried cuz its not coming then I'll be worried I really am pregnant... if you get what I'm saying? soooo be nice please(:
