Okay so me and my boyfriend had unprotected sex the day my period ended and then the next day I took plan b because I was worried... He didn't cum in me or anything but I know there is always still that chance I am also on the birth control patch and have been on it for about 4 months now, but the last time I wore the patch I put a fourth patch on when I was to get my period so I only bleed for 2 days. So the day after we had sex I took the plan b pill and it has almost been a week and I have like streakes of blood in my discharge everytime I whip and I'm worried because I am not supposed to get my period for 2-3 more weeks...
