Period is due today

Netta

For the past 2 weeks ive been exhausted! The week before my period i have tender boobs until it comes and i eat alot especially chocolate. All this week ive been having twinges pulling around my belly button pelvic cramping( mainly light) not much of an appetite but when i do eat i cant eat much. The bloating is unreal i wore jeans and had to keep them unbuttoned because it was uncomfortable on my stomach. I smell everything! I spotted yesturday light pink twice i never spot before a period but i got a negative test. Anybody else?
