Can you get a vaginal staph infection again? or could it be something else? all std test came back negative both times can it be a false negative?

Staph infections...: and yeast vaginal infections aren't considered STD's. Routine testing for STD's generally include Gonorrhea, Chlamydia and Trichomonas vaginitis only. Technically that's not a "false negative" test since you weren't tested for Staph. But, yes, you could have a Staph infection AND negative STD tests. However, Staph would be an unusual cause of vaginal infection. Hope this helps!

YES: Not that uncommon; however, I suggest repeating all bacterial and STD cultures.
