Outbreak or ingrown hair?

I’ve noticed a lump on my outer labia and it’s swollen and red compared to the other lip, it hasn’t had the usual tingly sensation beforehand and It doesn’t sting when I wee, I just noticed it when I was checking how hairy I was 😂😂 I’ve started taking my acyclovir already to be sure, I’m supposed to be getting lucky this weekend so I’m gonna be so mad if it’s an outbreak!! 🥺 what do you think?
