okay so i have read all of the answers about having some bleeding a week or so after taking plan b but my situation is kind of different. i had sex with my boyfriend as my period was ending but it wasnt completely done and the condom broke and he went inside me. i had heard that you cant get pregnant while your on your period but i went and got plan b about 40 hours later. that night i was nauseous and had diarrhea for the rest of the day and could barely eat anything. now a week later ive started lightly bleeding again a brownish colour but i just think it's really weird because its only a week after my period has ended, is this a sign of the pill or of pregnancy?
