Single bump on vagina

So I just noticed one singular bump on my outer labia right next to my vagina, it isn’t sore or anything, it is slightly itchy though, I haven’t had any sex in two months or anything sexual for that matter in 2 months, And I haven’t shaved or anything for the same two months (since I’m single I haven’t felt the need too yet) just not sure what it could be and wanted to hear advice, but if it doesn’t go away in a few days I’ll go see a gyno
