I have a dark spot inside my ?

I've been with the same guy for 2 years and we've been true to one another. I've been tested for most STDs. I shave everything "down there" at least once a week. Some of the hair is actually INSIDE my , along the labia. Along that area, I see really teeny tiny raised bumps and they worry me but I figure they're just hair follicles. I'm pretty sure they've always been there, even when I was a virgin. They've never hurt, bled or gotten bigger. However, I looked at my inner labia recently and saw a spot about half the size of a penny. It's a dark color. It's not raised or painful and it looks almost indented. It almost looks like a freckle. What could it be? I'm going to see a gynecologist tomorrow.
