this looks like yeast. i have the similar thing going on. i made an appointment, you should if possible to make you feel at ease. prayers for a speedy recovery.
this is a better picture, tbh it looks like herpes to me. probably it was just too late for the swab
what are your symptoms ? I think i had a similar case before . I usually wax but i had shaved that day . I had sex and i was not lubricated enough . it was with a condom . so im not sure if it was an allergic reaction . THe gyno told me it was yeast and i had an reaction .
it went away 2 weeks later. but that first week i thought the worst . it was itchy , and my vulva was red and a little swollen.
I did a sitz bath with apple cider vinegar and warm water to help ease the itchiness.
