So, me and my girlfriend were fooling around. I penetrated her vagina and we proceed to have sex for about 5 minutes, until we stopped. In that time, I didn't reach orgasm..I wasn't even close to be honest, we just decided to stop. Of course, I wasn't wearing a condom (dumb I know). What are the chances of her getting pregnant from precum?

Oh and we had did something earlier in the day, but I urinated after that..like once or twice (I don't know for sure). I heard when you urinate you flush out your penis? bah, I'm really paranoid right now.
