Thinning in the front?

[blumpnati]

I'm 21 years old and I could totally be paranoid but I think my hair may be thinning in the front. Wanted to make sure to get the opinion of you fine gents before I made an appointment with a doctor. Some background, I have two brothers in their mid 30's that are not balding. My father is in his late 60s and is bald on top, but didn't start balding until he was around 45, and his father was also bald. On my mom's side, neither of her brothers are bald and her father had a full head of hair his whole life.

Now I've always had kind of a straight lowish hairline, so I never really paid attention to it until recently my hair was wet and I felt like I saw an unusual amount of scalp. I also feel like I see a few hairs here and there in the sink while styling my hair in the mornings. Maybe my hairline is simply maturing, but do my pictures show potential signs of early balding?

First photo was taken with a flash/super-bright light to show the whole scalp showing through my hair thing.

Let me know what you all think, thanks!
