Brown spotting the whole week before my period (witch never happens) but then it showed up as normal overnight but a little lighter then normal then Saturday it picked up heavier and i was tired, dizzy and had head aches all day and i was nauseous and then over night i almost threw up and was really clammy now today i took a preg. Test just in case and it was negative but now my period is lighter then what it normally is on Sunday.... And i still feel "off" nauseous but not at the same time with minor headaches and tired as hell...
