I’m desperate at this point😭

I need help !! Idk what to do at this point, I’ve always had bad cramps the first 1-3 days of my period but sometimes they’re so bad that i cant walk& i cant take anti inflammatory meds because I was only born with one kidney. Heating pads relieve it a little but then my body ends up overheating since I already get slight fevers during my period. I also have an issue with crazy bleeding day 2&3 so I literally have to sit on the toilet for an hour or two because it’s so much blood and clotting.

I’m not sure what to do anymore, I need advice pls !!😭
