So not too long ago my boyfriend and I were having sex when all the sudden, the condom broke. We didn't notice for about four seconds and when he did he immediately pulled out. I believe there was no pre-cum or anything else of the sort. We drove around for 30 mins after that moment to find a Walgreens and he bought the Plan b pill. I took the pill but I'm still a little paranoid. 10 days later, I've missed my period by 3 days. I'm afraid to ask but.. Does this mean I'm pregnant?
