is it a yeast infection?

For the past month I unknowingly had a uti. Up until last week when I had unbearable pains and an odor when I pee so I went to the dr. and was treated. I believe I had a uti prior to that week was because of my super dryness during sex. I just couldn't understand why I was so dry. I was so dry that i wouldnt even have discharge...NONE!! I would drink water and still be dry. After I finished my uti treatment I found a diflucan (one dose yeast infection pill) I forgot I was saving some months ago. I figured it would be a good idea to take since antibiotics could give yeast infections. that was a week ago. So now since I have been drinking half my weight in water I have been having a weird consistency coming from my vag. It's watery but still has a little thickness to it. Idk if it's a yi or discharge for the first time in a long time. Also according to my eve cycle I am in my fertile window...
