I'm Not Sure If I Have A UTI Because When

I'm not sure if I have a UTI because when I did in the past (a few years ago) I had blood in my urine. This feels very similar with lots of burning when urinating. However, I have recently been on high doses of antibiodics for diverticulitis and am wondering if this could be a yeast infection. I don't have a discharge or smell. I'm leaning more to the UTI but I'm not sure how to treat myself until my doctor's appointment tomorrow. This burning is really getting to me.
