Help, condom used, period late?

im 15.i had sex with protection, about two weeks ago, all went well, and the condom was neither torn or broken. i have been fingered also around that time, also with clean fingers, if not, with a tiny bit of dried pre-*** on his fingers. my period was due 5 days ago, and nothing has happened, i have been experiencing normal white discharge, and stomach cramps, as normal on arrival of period. im freaking out a lot and i don't see just how i could be pregnant! any help?
