UTI hasn’t gone away?

Katelyn

So I got a UTI Jan 11-12th and my doctor prescribed my meds for it. I also had another uti around Christmas and also got that taken care of with medicine and that cleared up with no problems. But this second uti it took longer to heal even though she gave me more pills than last time and I’ve finished the pills now but I still have a faint urge to pee and it hasn’t gone away and I finished the pills two days ago. Any advice on what to do or what could be wrong?
