Am i balding 19 y/o

[3rdDecade]

Hi I'm new to this forum. I'm 19 years old and always had a fear of going bald due to my family history, number 1 being my mothers father! He was a Norwood 4/5 at 21 and by 23 a Norwood 6/7. My cousin (my mothers sister son) same maternal grand father is 21 and resembles him. My father still has all his with a mature hairline. My hair identically resembles my fathers, whereas my maternal grandfather had curly, blonde, thin hair.

In the last 2 years I have noticed the corner edges rise by 5mm, bearing in mind that area was always thin producing baby hairs, is this just a mature hairline or the start of mpb, honest opinions welcome. I've always had widows peak, never been straight.

My question is: Do you think I'll be a Norwood 5 in 2/3 years time using the above info as best you can and likely possibilities, any response would be great.
