Bump on vagina!!

Hi ladies, so I recently noticed a bump that is on the inside of my inner labia. I noticed it a couple of months ago and thought that it was an ingrown hair but then recently had a wax and realized that it’s still there and it’s super noticeable to feel now. its not painful or anything but you can feel like a hard lump in my lip. I already have a doctors appointment scheduled but I wanted to know if anyone has had anything similar.

(Sidenote: I’m positive it’s not an STD. Hubby and I have been together for 7 years.)

Any knowledge or advice would be super helpful because it’s worrying me!
