i was in almost the same situation this summer. I banged this girl a couple times and one day she says shes pregnant and i get a shitty job and all this other shit. but oh wait the baby aint mine and by the way its my best friends. she got into coke and shit so me and my buddy dropped her off at the hostpital and boxed out his car. so yea just wait it out and prepare for the worst but hope for the best.
