I'm I going to grow more?!

I'm I going to grow more?

i am 18, turning 19 in a month and I have grown .70 of an inch since last year( I am a late bloomer and never had a big growth spurt) I only put on 2 3/4 inches my entire highschool career. My voice also started cracking a year, and facial hair and fine chest hair are coming out. How much height do you tihkn I can put on? And I am 5"9.7 my Dad is 5.11.5 and mom is 5'4, both of my grandfathers were 6 feet.

If you are lucky you may grow a bit more.

You can actually keep growing until the age of 20 or even 21 but it is uncommon and rare.
