Pregnant, or to easily convinced?

My period is due in 2 days according to my "flow chart"...im obviously not late for it yet, but im having serious pregnancy symtoms. Im crampy, bloated, have a metallic taste in my mouth, and my boobs ARE KILLING ME 😔 even though im not late yet, i took a test today; you know, the clearblue that SAYS it can tell 5 days BEFORE a missed period, and it was negative. Hmmm...still to early to tell? Or really not pregnant?
