Hi, my boyfriend and I had sex about a week ago, and I was on my period (first day). About 5-10 minutes in, the condom snapped. He hadn't cum yet, nor pre-cum. I took the Plan B pill a few hours after (maybe 3 hours?) and I've been fine since. However, just as i was using the restroom, what I believe to be a piece of the condom fell out. My period has been as normal as usual, but now I'm just a bit nervous and I'm letting my nerves take me over. Any answers would be perfect!!!
