Will or How can i grow taller?

I think im a late bloomer. I don't have any facial hair yet my voice isn't that deep. Im 17 and a half and about 5'11". My dad is about 6'1" my mom is around 5'7" and don't automatically ume im going to be somewhere between 6'1" and 5'7" because my cousins (mom's side) are about 6'3" and both of their dad's were about 5'9" and there mom (my aunt by blood) is about the same size as my mom. That means my moms side is tall. And on my dad's side its mixed between 6'4"-5'10". The only thing in can think that might have effected me is i started working out around age 14 but nothing extremely heavy, i thought that it was a myth that lifting weights stunted growth, unless you were lifting really heavy stuff with your back. So statistically speaking what are the chances i will grow?
