UTI symptoms- urgent care or wait till Friday appointment?

So I’m 13 weeks pregnant and have some UTI symptoms. They normally go away after a day or so but this one is hanging on and is going on five days. It’s starting to hurt- both while urinating and back/hip pain while stationary. Tomorrow is Monday, but it’s a holiday. I have a prenatal appt with my OB (and my fav dr) on Friday. I sent an email tonight but likely won’t get a response till Tuesday. Do I call the nurse line or urgent care tomorrow, make an additional appt (and pay another fee for an urgent care visit) or just wait until Friday? It’s not unbearable, mainly just uncomfortable.
