I think it might be. I think i'm getting one too. First question is: how long has this been going on? Whenever I feel any symptoms I try to drink insane amounts of water to prevent it from getting worse. I usually stop it there, but if the pain is severe or you've experienced this for a few days you need to get antibiotics to kill it. They sell test strips at the drugstore now to let you know or not. Some doctors will let you call in with your results and they will give you a prescription for cipro. In the meantime if you are in pain go buy azo-standard. It helps a lot. If you are sexually active and on birth control use condoms while taking cipro. Cranberry juice also helps. Not the cranberry coctail with all the sugar, get the natural kind. Don't drink caffiene either. Good luck! Hope this helps.

Im not so sure that is a uti. I have had several and you generally feel unwell, tired and the most telling sign is the burning and stinging (from where you pee) right after you go and also a contant feeling like you need to pee but not very much comes out.

The adominal cramping you describe sounds like somethingmore serious like and infection or (if you've had unprotected sex) pelvic inflmatory disease.

I think you should see a doctor.

You could also have bacterial vaginosis. It is a very common bacterial infection "down there" it can cause cramping and such. You may have a uti, but you would most likely have burning. But, it could also be a kindey infection or kidney stones.
My advice would be to go to your doctor and make sure. It is probably something simple that can be fixed easily and you will not have to suffer anymore!
