so i had a 1 night stand with this girl and while we were having sex the condom broke(about 5 mins into it). i pulled out asap and put a new one on an finished. i am now worried and don't want to get a phonecal 9 months from now saying i have a kid. i was in her for about 2 seconds with the broken condom. also i noticed that the other condoms that we used were red tinited from blood, what could this mean. should i be worried?
