Uti? Pregnant

So last week I asked my dr to do a urine culture to test for a uti and yesterday I went back and they said they had to repeat it but that’s it. I’m now feeling even worse, I feel a little dizzy but could be anxiety, and then it burned a couple times when I peed and my urine has been darker. Idk what to do, I’m 39 weeks pregnant, is it ok to wait to call in the morning or should I go be seen now?
