Had a culture and urinalysis done and, results were negative but i still smell a slight ammonia urine smell in my discharge not strong, and had no sex?

Here are some ...: Clinically, you're okay. As to the smell in urine & vaginal discharge, that is personally unique but normal to reflect the amount of excretion from your rich apocrine glands to interact with the bacteria in genital area as well as the expected presence of ammonia in urine. In fact, exposing urine to air for 30 minutes will surely make urine stinging. So, as long as having normal UA..., it's ok.
