I had unprotected sex with my boyfriend for the first time. This only lasted a max of five minutes, and we did it on and off. (Only a minute each time). He never did ejaculate when we were having sex, or anything before hand. But then someone told me I could get pregnant off of precum. I was never told this in school, or even heard of this! This scared me, so I went to get Plan B(One Step), just in case. I took Plan B around 13-14 hours afterwards.I am worrying myself to the point of exaustion. Is it possible I could get pregnant? I need some advice.
