My Story/Am I likely to go bald or am i already balding?

[Cris21]

Hello my name is Cris and I am 17 years old. Allow me to tell you a bit about hairloss in my family. Almost all men in my family have kept their hair all men on my fathers side and all men on my maternal grandmother's side they all kept their thick full heads of hair. My maternal grandfather's side most of them have their hair except for him. Now as for me I don't look like him at all or at least i don't have any of his psychical traits i look more like my father and maternal grandmother. Now i've been paranoid about this for some time because my maternal grandfather started receding at 16 years of age. Even though my hair texture isn't even like his or none of my looks i still worry and him, my mother, my grandmother, my father everyone is telling me i wont go bald or im not going bald and my grandfather said i would be seeing signs now if it was going to happen. Anyways here is some pics of my frontal hairline sorry for the lengthy post i hope your opinions don't confirm my fears.
