ok so i'm 14 and i still haven't started my period yet, i'm the last one of my friends who hasn't.

about two nights ago i woke up with an AWFUL stomach cramp and couldn't sleep. then yesterday i had brown discharge. and then today i had the brownish discharge again but when i wiped, there was a reddish discharge. it looked like a little blood mixed with discharge??
so i have NO clue what it is and i was actually wondering if thats my period or if i might start soon.
