Okay so me and my boyfriend has unprotected sex two days in a row but the first time he wasn't even close to cumming and the second time he pulled out, I took plan b 20 minutes after the second time and it was within the 72 hours for the first time. It was 4 days late, but I have taken plan b before and I was late that time too. I am already on my period and it's my 3rd day and everything seems to be fine but I have major bloating and my breasts seem bigger. Can I be pregnant if I am on my period and took plan b?
