concerned bump - infected ingrown or herpes?

hi - i am concerned about a bump on my vagina. i had sex with someone on 10/5, went to my obgyn and tested negative for herpes.

a few nights ago i noticed a bump on my vagina and picked at it. it initially looked like the first picture but when i woke up i noticed it looked differently. like the second picture. should i be concerned this is herpes? or did i possibly infect my ingrown and this is a zit?
