I have horrible menstruation. Horrible. The cramps make me cry and be nauseous (I've had to stay at home on more than one occassion for them and I NEVER miss school), the blood flow is relentless (7 days usually), and I get a severe headache and mild fever. I have a suspicion that it's genetic, considering how my mother once bled for 12 days. Exercise seems to help, but I was wondering what else I can do? I'm sick of feeling like this a week every month. I'm at the end of my rope!
