Pelvic pain having to pee every five min pain goes in to my right side and my back could this be kidney stones or something worse?

Uti or stone. This can be a sign of either a bladder, or kidney infection, or a kidney or ureteral stone. You may need an antibiotic if it is an infection. If it is a stone, you may require surgical intervention or simple watchful waiting. Either way it sounds like you should see a urologist, or go to the emergency room if the pain is severe or if you are sick.
Either. Seek medical attention. Could be stone or a kidney infection. Either should be dealt with asap.
