Naproxen
"So when I started getting my period at about 13 I had the WORST CRAMPS EVER. Like I'm talking over the toilet, in the shower, missing school, and stuff like that. Typically it was only the first, rarely the second, day Of my cycle I would stay home or come home in bed feeling like my insides were flipping inside out. So after a couple months of this my mom got worried and took me to the doctor who told me I should go get an ultrasound on my uterus to make sure that there wasn't extra blood flow, extra lining, or anything. This is mostly because I didn't have blood clots so she wanted to make sure there wasn't something that needed attention pronto. nothing came up in the ultrasound. So I got prescribed naproxen and it's a LIFE SAVER!!!!"
