I would guess that the equivocal result most likely represents a negative result, not a positive one. I’ve only had three people in my entire 40 year career that had an equivocal IgG for HSV 2 and went on to have a positive western blot.
None of those drugs would cause an equivocal result on the HSV 2 IgG test.
If you have an equivocal result in July, I think you should believe that you are uninfected. If you can’t do that, pursue the western blot for greater certainty
