[Female health question] [NSFW?] Why do I get such painful cramps during my period? How can I relieve the pain?

Sorry for such a personal question. During my period, I get the worst cramps. I get super dizzy and faint/nauseous. I also throw up a lot. It gets to the point where I am almost doubled over and can’t move because I am in so much pain. I went to the doctor, got blood tests for anemia and other things. They all come back negative. I have a regular and fairly healthy diet. I exercise regularly. I’m not sure why they get so bad. I’m thinking it’s hereditary, as my mother gets them just as bad, but I don’t know. Is there any way I can alleviate the pain? I take Midol for it, which works for a short time, but I would like something more long term.

(Not sure if this would be NSFW but I’m labeling it as such just in case)
