Does This Sound Like A UTI?

First, let me say that I am going to my doctor, I just want opinions. I've been peeing A LOT. I drink lots of water, yes, but I literally always have to pee. I go pee, all is well, then literally 5 minutes later I'm back in the bathroom because my bladder says "whoops, never mind." It hasn't really hurt until today, but idk if period cramps are to blame for my sore bladder, (I'm currently walking around like smeagol because it hurts so bad to stand up straight) it hurts so bad. Does this sound like a UTI? I've never had one before. My man is away for work sonwe haven't had sex in 7 months so I don't have an std
