Thought it was a UTI, but no?!?!

I am currently cycle day 22. For the past week I thought i was getting a UTI, frequent urination (not always a lot comes out) and low back pain on one side. It never developed into anything which normally happens in 2-3 days for me. I had my urine tested and it was fine. I have also had creamy cm, I get hungry a lot more, and I have had a lot more gas these past few days. I haven't tested yet.
