The test at your doctor won’t get reported to the panel physician but if you are asymptomatic sure you can wait. You may read about cranberry juice. Don’t know if that has ever been proven. Don’t over hydrate. You can really do harm to yourself if you drink too much water. Symptomatic would mean having urgency (feeling like you have to pee often), pain, burning, visible blood in your urine, etc. Drinking enough fluid to wash out the bladder, kidney, ureter, etc. is your best attempt at treatment. If there is a low grade infection or something else going on the first step would be a course of antibiotics. As your research would have shown you if you are a woman UTIs are pretty common. Surprised you haven’t heard about them. Maybe you have heard the term bladder infection before. Like I said this is likely easily resolved.
