Vagina

Im 19 weeks and I've been drinking sodas because Coke will take some of the sickness away. But u feel like there is a certain spot on my vagina where I pee it feels itchy more like burning. When I sit down or anything it bothers me. Feels like it's just in one spot? When I go to wipe it feels like a relief. I don't wanna itch it if it's not driving me crazy. Could I have a uti.?
