Uti didn't go away after antibiotics what to do ?

Got my first uti almost a 2 weeks ago. I am in my early 20’s. I was prescribed antibiotics. It seemed to be going away but the last 2 days into the 7 day dose it seemed to be coming back. So , 2 days after I finished the meds I took an at home uti test. First one came up positive for a utI but second test came up a possible trace. I don’t have insurance or the money to pay for more doctor visits and testing. Is there anything I can do! ?
