embarrasing body hair

I shaved my belly button hair back in 7th grade (I am now 21) because I have very dark hair. It was ok at first but over time even when I shaved it there would be black specs left where each hair was. They can't be plucked because the surface is smooth, they don't peek out at all. It is very noticeable to the point where I hide myself when a situation (like the pool or beach or changing in front of someone or sex) arises. I don't even think waxing would work because most the time even if I find one to pluck the follicle is still black. The whole area is darker now, there are darker patches of skin in that area. Does anybody know what I can do? I am tired of not having confidence because of it. No other girl I know has this problem, and when I look it up I find nothing about it. I have also tried bleaching the hair, it is so dark and course that it does nothing.
