I'm 17 and worried about Height?

Im a 17 year old male in my junior year at high school and currently 5'7''. My dad is around 6 feet and my grandfather on my mom's side is around the same. It makes me really angry that I have only grown 1-2 inches since the 8th grade. To me that isn't normal. Am I just a late grower or am I done? Side Note: In the stages of puberty, I had full pubic hair at 14. Any help?
