UTI- Where do I go?

So I’m 25 weeks pregnant and I’m pretty sure I have a uti. It hurts and is really painful when I pee and I feel like I have to go all the time. However I don’t know if I should call my primary care doctor to schedule an appointment , my OB, or go into urgent care. I have private insurance so my urgent care isn’t at the hospital . It’s a private building and is hardly ever full. Should I go to urgent care to be seen and get a prescription right away? I know my OB leaves the office around now, and I’m not sure I’ll be able to get an appointment with my primary. Thoughts?
