What should I do

I woke up yesterday feeling like a had a uti, but the feeling went away, today same thing and now I have a yellowish discharge. I also have a slight dull pain on my right side. I thought I had a uti about 2 weeks ago and doctor said no. Now I'm worried I did have one and it's getting worse. I've also had temp of 99 the last couple days. My doctors isn't open til Monday and I have an appt. Tuesday. Should I just wait or should I go to the hospital and make sure I'm ok. I'm just so worried that I've had one this whole time and it's getting worse.
