period cramps are killingggg me.

I'm the type of person who doesn't like to miss a day of school, due to falling behind, or slipping up my grades. But every time I have my period, the first 1-2 days I don't even wanna go to school because it hurts so bad. and there's absolutely nothing I can do to make it feel better. I don't know if this is normal or not, but if it is normal, I can't quite imagine how it could feel worse.
