pelvis/bladder problem

It doesn’t hurt to pee but when i’m almost done, right before the pee stops coming out, my whole pelvis hurts. It’s not my actual vagina it’s like the whole area above it. possibly could be my kidney. i don’t think it’s kidney stones but it might be my bladder or pelvis. anyone else experienced this ?? also i haven’t had sex in a while so i don’t think it’s related to that. i could just be worried for no reason and it could just be a pain that will go away and doesn’t mean anything
