Had a UTI last month went away. Urine culture today shows negative. Still have urgency and frequency for over a month and couple weeks will it go away?

Urgency & frequency. Let's clear up a common misunderstanding. Unless you're pregnant, there's no need to get a urine culture after finishing a course of antibiotics because we're not going to treat asymptomatic bacteriuria in adults, certainly, not in those who have an indwelling catheter. But you still have UTI symptoms despite negative urine culture so you need to get tested for sexually transmitted diseases.
