Me freaking out about nothing?

[playsupermario3]

Hey guys, this is sorta awkward and I know I'm just being dumb, but I can't get it out of my head that my girlfriend is pregnant. The thing is, we didn't have sex. I just sorta cam all over her chest and stomach and I'm paranoid that she got some down there and Is now pregnant. What are the chances of that happening? We cleaned up afterwards and I don't think anything slipped down there but I donno. Any thoughts? Thanks guys
