Period problems?

Okay been convinced I was pregnant, all the symptoms, tired, nausea, dizziness, smelling everything, crazy dreams none of these are period symptoms for me. Then I started my period a day early, which is unusual for me, was heavy as all get out for two days clots (normal for me) One was a bit bugger than I'm used to but otherwise normal, day 2 very light spotting day 3 gone completely. My period has ALWAYS been 7 days with the last two being spotting. and I still feel all the symptoms as before, anyone have any insight on this?
