I have a uti since last week Monday n the next day I went to the doctor and he gave me some antibiotics n in a few days I felt a lot better until I had sex and now all my symptoms are gone except 1. I have now made my urge to pee more strong and I don't think the antibiotics is helping because it's getting even stronger that I can't sleep I pee always every 2 min. Should I go back to the doctor? What can I do to make it stop? I already sent of my urine last week Thursday but they haven't contacted me so I don't know what to do.
