Should I Be Concerned?

I’ve been drinking a lot of water in hopes of flushing out a UTI I think I have, I was told that was possible if it was small enough. It’s been some days, and basically, if I don’t drink a lot of water, it will hurt when I pee, but if I do, it doesn’t. However, sometimes there’s still that distinct UTI odor, so I’m wondering if I should be concerned? Is it possible the bacteria could travel to my kidneys without pain? If it gets to my kidneys will it be too late?
