UTI during pregnancy

So I woke up this morning I'm 14 weeks and a day and I started having pressure on my uterus and pee area and I been having to feel like I had to go to the bathroom Constant but not much urine is coming out but once I try I have pressure I read the symptoms of a uti and looks like I have one so I probably am in the beginning since I just started feeling like this this morning, should I consult my doctor about it, or just try to drink cranberry juice and hope it's goes away I been drinking water like crazy and trying to flush my system out, but this is just so uncomfortable and I'm worried it'll affect my baby! Any ladies had this problem before and what did you do?
