I'm really freaking late....

Katelyn
Okay about 2 weeks ago I had sex with the guy I was talking to. Spur of the moment thing, wasn't really expecting it BUT it happened. And it was great too. Well the ass hole just dropped off the face of the planet. I was super hurt about that. But now I'm Almost a week behind on my period. How long before I could possibly take a test??? Don't want to say I'm freaking out because I'm doing my best to keep my cool but this is kind of freeking me out now.... Help!
