I Went To The Walk In Hospital Clinic For A

I went to the walk in hospital clinic for a vaginal discharge that started clear and small and got worse by the day. I had a swab of the vagina and was given medication in the form of a shot and yeast infection meds and other meds metronidazole included. My test results came back "negative for everything' they said. The symptoms started had started to go away but since my results said negative I did not complete the meds. Now the symptoms are back. ?????????? I do not have sex without a condom and rarely have sex.
