So my boyfriend and I had unprotected sex today while im on my second (and heaviest) day of my period. He came in me and I freaked out and tried to push/wipe it out. My period usually lasts 5 days and I have a longer 28-30 day cycle. I also had taken plan B two weeks ago so I don't know if that might mess up my cycle. What are the chances I could be pregnant? And should I rush to get plan B again?
