Have vaginal discharge and pain, gynecologist doesn’t believe staph infection, what do I do next?

Tested negative twice for gonorrhea and chlamydia. Have vaginal discharge and pain. My urethra feels swollen and I can pee frequently although I can also hold on to my urine. I have had cipro, azithromycin, doxycycline, metronidazle and levoflaxin in the past two months. No improvements. Waiting for smear results but swab showed lots of pus cells and was shown to be moderate staph. My gyne didn’t seem convinced this was causing the issue. I’m at a loss about what to do next.
