i'm tweaking TT

hii, I need your help because I don't know what to do anymore. For months, my period has been more painful than usual, to the point that I can't walk, I have trouble doing things, and worst of all, I feel nauseous and vomit. For health reasons, I can't take more than one painkiller, but that doesn't help at all. I'm afraid I might have something serious, and what's worse is that the pain is so bad that I've started crying. Please give me some tips on how to cope with this.
