I was having some pms/pregnancy symptoms 5-7ish days before my period....i.e. dizziness, tender breasts, cramping,extreme fatigue...and then started my period 4 days early. Not nearly has heavy, but I wouldn't consider it spotting. Has lasted for 6 days and is brownish pinkish in color....very light. Since I "started" I have been nauseous, thrown up, dizzy and fatigued. I have never experienced this during a period before. I'm 27 aND I'm not on birth control. Had endometriosis removed at 21. Could I still be pregnant?
