Is it herpes or yeast infection? Help please

14 weeks after the first manifestation of this kind, i took a blood test, specific serology igg/igm for hsv 1 and 2 and it turned negative.
ive read that antibodies can sometimes take longer to form so idk what to think
gyneco and dermato told me that it does not look like a typical herpes outbreak but in medicine we never know
what do you think?
