PLEASE HELP ME..

My period was due yesterday, i know its only been one day and i shouldnt be jumping to conclusions.. I've been having mild cramps, headaches & nausea for a couple of days now. I wake up in the middle of the night catching hot flashes. I sleep all day much more than usual. Since the day before yesterday i've been having loads of white milky discharge. Maybe this is all in my head, but i know for sure the discharge is real. Should i take a test or just wait to see if AF shows? Im really hoping this is my month..
