Abnormal growth pattern?

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, pimples 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 soemtimes 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?

Abnormal growth pattern?
Its not uncommon to have years where you grow more then others. If you don't stop growing at 21 then your pituitary gland has a problem.

Reply:Pal it happens after stagnated growth, and it's normal. Please don't bother about that.
Reply:My boyfriend's family has experience some of the things you are speaking about. His uncle had thought he had stop growing and when he was 25 he grew and inch. My boyfriend's brother is going to be 19 next month and he still has a face of a 13 year old. He barely has any armpit hair either. There can be many things that are causing your slow growth but if the doctors aren't concern don't worry yourself.
