I'm 17, 5'2 and 110 lbs. Every month when I start my period, I get severe cramps to the point that I am dizzy, near fainting, and getting cold sweats. I get diarrhea and vomit and I get very dehydrated. I sometimes get cramps between periods and it sometimes hurts like menstrual cramps when i have sex. I'm worried I have endometriosis. Is all that stuff normal? :
