Just the other day I started having to go to the bathroom more frequently, right after I urinate I get the urge to urinate again. Now I go to the bathroom a couple times in an hour. It doesn't hurt to urinate and every time I do urinate its like a normal amount of urine. I started taking the pill AZO, it didn't help at all. but before I started taking it, my urine was clear, with maybe only a hint of yellow occasionally. Could it be a uti? I'm a female that is sexually active.
