Is My Crown Balding Or Is It Just A Hair Whorl?

[Lucas Vanham]

I'm 18 and worried. I don't seem to be losing that much hair when I wash it but I do find any where between 5 and 20 hairs on my pillow every night. (now that it's been very hot for a couple of days it's been around tweny but notmally it's way lower.
The last 3 pictures are from 2 to 3 years ago to compare.
