Answers please??

Hey guys. So I guess this is sort of a dumb question... but my boyfriend and I had sex with a condom, he didn't finish, but I'm still somewhat worried I could be pregnant. I made him stop quite a few times because I'm still paranoid from my last experience (which was obviously not a good one). I also had quite a bit of discharge while we were having sex.. what does this mean?? I just need reassurance that I'm not pregnant
