lump/bump on my upper labia minor

Hi everyone,

I read about Bartholin's gland cysts and abscesses, but mine is definitely up higher/more forward than that (like, closer to my clitoris area as opposed to at my vaginal canal...not that it's anywhere near my clitoris - I'm just trying to explain where on my labia minora it is, if that makes sense)...so it's not really anywhere near the area of the Bartholin's glands.

Anyways, I found a red bump on my upper labia minora. It is about the size of a pea and it hurts when I touch it. I just had unprotected sex with my partner a day ago and now I am scared that it can be something potentially harming to both of us.   

I hope some one can help.
