Please help me. What is this?? Is it Herpes?

i went to dr last week for weird discharge and got treated for yeast couple days later this sore came , never was a bump just a sore

Is it sore? Or itchy?
Doesn’t particularly look like herpes.
Did the doctor do a std screen for you when you went to them?
If they didn’t I would suggest going to get a full std panel done (ask for herpes). That discharge doesn’t look like the color or consistency of a yeast infection I would get it checked.

no, not at all

i called my dr i was tested for std everythinh came back negative. only thing i used other than the pill he gave for yeast. was flaygl gel do you think this could be a reaction from the gel?
