UTI???

So i went to the walk in clinic to test for a yeast infection and other vaginal infections. I have been extremely itchy and had clumpy yellow discharge basically my whole pregnancy but the itching is getting unbearable. I go get tested and they told me i have a UTI. Yet i have absolutely ZERO symptoms of a UTI.. my only symptoms is increased lumpy yellow thick discharge and itching. Could this be the UTI? If not this doesn’t make sense to me lol
