Okay, so my boyfriend and I had sex last night and the night before, both times with a condom. He squirted some precum and he pulled out and we changed the condom. The condom didn't break AND he pulled out before he finished. However, I'm a little worried because it looked like the condom was rolling up a few centimeters...is that okay? We checked the condoms after and there were no signs of leakage. Also, my fertile window begins in 3 days, so my period ended 3 days ago. I'm just concerned, and every time I get concerned like this I want to take a Plan B pill, which I know isn't healthy. Any advice?
