vagina pimple or something else? HELP

lili

hey y’all, this is awkward but i’m worrying so i just noticed a bump on my vagina lip there isn’t any pus or anything it’s just red and its medium size. there’s only one not multiple but could it be herpes or just a vagina pimple? ive only been with one man ever and we’ve been together for about two yearsish. help i’m worrying. UPDATE i just discovered the bump today and then i just went to the bathroom and it already popped it was oozing blood and white stuff! what could it be i’m scared.
