Do you think this is a herpe blister or ingrown hair?

i havent shaved in two to three weeks and recently i shaved about three days ago and this morning this blister appeared its not painful, nor have i had a fever or any herpes symptoms, but its weird looking and im scared, my bf tested positive for herpes but i tested negative a couple months back, we’ve been together for two years now tho (no cheating we talked abt it) so we assumed he had false results esp cus we’ve never had flare ups before, could this be herpes or a result from shaving ? also it’s located way away from my vagina, it is at the top of my pubic hair zone area.

u should go get it checked out if it looks different if they think herpes they will do a swab
