ok so my boyfriend and i had sex for the first time 4 days ago and he pulled out but we were both really scared so i took a plan b pill right after. i wasnt ovulating when it happened, i'm supposed to get my period in 2 days and i've been getting the symptoms i normally get before my period (i get really short tempered and annoyed easily a few days before my period). so what are the chances i'm pregnant, i'm so stressed about it neither of us can sleep
