I was spotting of four days before my period and I was very fatigued and new something wasn't right and today I woke up with extreme pain and upset stomach. I have puked my pain meds aren't helping much and I don't know why this just hit all of a sudden it hasn't been this bad in awhile what could be going on or does endo just decide to hurt more once and awhile? Should I be worried or is this common? I a, just so sick of going into emergency and them treating me like crap.
