UTI or something else?

Je

So I'm having this weird feeling that started yesterday. I'll be relaxing and randomly feel this strong urge like I need to pee but then it goes away. It doesn't burn when I pee and my urine is clear. It doesn't constantly hurt its just random. I'm not sure if it's the start of a UTI or just baby girls head pushing more on my bladder or cervix making me feel like this. Any one else ever have this? It's hard to explain. I'm 23 weeks
