Used monistat. I have one tiny whitehead on vagina lip (or vulva?) Not painful/itchy. Could it be herpes? It's been a couple days. Paranoid/worried.

Probably not. It's probably not herpes simplex virus of not painful at all since it appeared. Get tested for all STDs including gonorrhea and chlamydia , herpes, etc. Stay calm and get tested and see your OB/GYN for your first Pap smear. Good luck. .
