Growth question?

I am an 18 year old male( turning 19 in 2 months) and I have grown 3/4 of an inch in the past year. However my growth as always kind of been steady, I never really had a huge growth spurt( peak was 2 inches in one year 14-15) At 5'8 3/8 at just 15 my growth pattern told me that I was going to be 5'11, well it never happened( Dad is 5'11 mom 5-4-5'5) Both of my grandpas were 6 feet). when I turned 17 I had grown only to 5 foot 9. I Thought I was done growing( even though I looked like a 14 year old without any hair on my face) Well when I turned 18 during last summer, all of a sudden my voice started cracking, started growing light facial hair, fine chest hairspimples all over the place and grew 3/4 of an inch to my current height of 5'9 3/4. I still have very oily skin and my voice still breaks occasinaly and my facial hair grows very slow. Do you think I am going to be one of those people who doesn't stop growing until 21 or I have stopped already? Has anyone hear experienced this

Growth question?
This sounds like a late growth spurt. I would get your parents to set an appointment with an endocrinologist. He can take blood samples and test for the various hormones in your system that affect growth. Since you seem to still be growing I would not worry to much at all.
