I think I'm getting a UTI. According to Glow, I'm 3w5d and I've had that heavy, full bladder-ish feeling for a couple days. I thought it was my uterus stretching, but tonight it was slightly painful to pee. Usually I'd start taking a cranberry supplement (I hate cranberry juice), but it says to consult physician if pregnant. I'm sure it's the standard cya message, but I don't want to mess anything up. Dr. Google says UTIs are common in pregnancy, but I'm worried. Is there any relief to ward it off?
