Help! Is this herpes?

i recently shaved 5 days ago and had unprotected sex that night two days later a pimple popped up in between my thigh and vagina lips i assume it popped overnight last night and now looks like this im freaking out and not sure what to do because the closest appointment is next month

im no doctor but it looks more of a boil . hope everything go well . i would go get checked to be sure .
