Me and my girlfriend had sex on November 1. Her period ended October 20. We had sex for 5 minutes unprotected before I put on a condom. I know precum only gets you pregnant if it pushes sperm out from the urethra with it. The thing is I masutrbated the night before but I urinated at least 3 time before we had sex the next day. I know there are always chances of her getting pregnant but I just want to be reassured whether these odds are high/low. Thanks.
