Am I balding or is it mature hairline ?

[devilsmaycry]

I am 17
I always had a high hairline from childhood itself.
But nowadays I noticed that my hairline is receding .
Will this lead to baldness.
OR will the receding process stop ?
I don't know any history of people in my family balding this young.
My father is not bald . Only has receded hairline.
His hairline has receded about 9 yrs ago but stayed at the same line.
He has the same receded hairline before 7-8 yrs and now.
My uncles in mothers side have lower hairline and more hair than me ?

AM I BALDING OR IS IT MATURE HAIRLINE ?
