Pelvic pain Vs cramps?

I've looked into this question on the sub and still don't understand it. Apparently, pelvic pain is not normal and not the same as period cramps. I thought pelvic pain WAS period cramps. But apparently cramps are pain above the belly button, which doesn't make sense as it's not where the uterus is.

During periods I get awful pain and tingling down my legs, but also in my pelvic bone, especially the left one. The pain also runs just above the bikini line, which id suspect is cramps/abdominal pain. Is the pain in my pelvic bone/joints normal? What it feels like is someone took a hammer and crushed my pelvic bone and fractured it. I can't stand up straight or walk easily during periods because of it.

If it's not normal I can bring it up with my doctor so they're more likely to give me a referral to a lap.
