Did i stop growing?

Im nearly 17 and im 5'8". My mom is 5'6" and my dad is 6' tall. I've only grew half an inch in the last 2 years. I hit puberty a few months before my friends and that time i already had a growth spurt from 6th to 8th grade when i went from 5' to 5'6" since then i only grew 2 inches. Please help me out because im really worried im not gonna grow any taller.
