HELP PLEASE!!

Jenni
So i'm 5 days away from my period and the past few days probably 3 or 4 i've just felt weird. i think i'm pregnant but when i tested 2 days ago it was negative and now i know it was too early but my symptoms are:
•very sore nipples
•very vivid dreams 
•a little nauseous 
•light dull cramping (i've never cramped this far away from period)
•and EXTREMELY emotional i literally just cried for an hour straight because i didn't get my baked potato when i wanted it(i'm never like that either 
•and obviously craving food 
*im going to test later on again but i wanted everyone's opinion.(please don't think i'm crazy)
