Please help

So my period has ranges anywhere from 24-33 day...it's currently day 32 (im 14) eve says im late by one day. I haven't had sex but I've been fingered and such.. my vagina feels a bit dry which isnt normal for mebut there is some white creamy discharge. Is this normal to get before your period? Im freaking out over this. I had cramps one morning a couple days before and thats it..im really worried can someone explain please.
