17 years old, receding hairline?

[Idfrie]

Hi I am 17 and i am extremely worried about my hairline! I think it has been receding back but I am not sure... I have always has a high hairline but I would like to know if you think it has receded. I pictures from 6 months ago and some recent ones, I am not really sure if there is much difference. What do you think? how badly has it receded ? what stage do you think I am on the norwood scale? any advice? Should i start any treatments? Please be honest. (Recent images) http://imgur.com/a/lISDl

Looks normal to me...maybe it's like that now because you keep pulling on it?
