Someone please?

So I was supposed to start my period on the 8th but now it says the 14th...well lately my boobs have been really sensitive, my stomach has been on and off upset after everything I eat.. I've been nasceous a lot and constipated.. Headache and always feeling tired. My period has been late everything month this year since I've been with my bf.. But I don't know if I should over look it this time? Im going to see if I start tomorrow... But should I test? Last week I had a lot of white discharge, but not a lot this week..
