Yeast infection

So I’ve been two the doctors twice already and they told me I had a yeast infection so they prescribed me this 7 day vaginal cream that I have been using since Friday, and it is now my 4th day and I honestly feel no difference. I woke up at 5am to go pee which burned so bad and now I have a pad on bcs every couple minutes I have an urgency to pee very little. I literally don’t know what’s happening to me but it’s so painful. I’m 17 btw, and I’m going to the hospital after school hoping I get better :/
