5ft 2 in only at the age of 14...?

I was still shorter at that age. Then i began exercising much. I would jump with my hands stretched high and parallel to each other. Everyday morning, a 100 times. I have grown over 5.5 now. Try the same if you are too worried but it seems to me that you are growing normal. No need to worry. You will grow till you have your Adam's apple and till your voice becomes manly.

You are only 14 and your height may increase for another 5 years. You can do pull-ups for increasing your height. What do you mean by growth spurt? You don't grow tall overnight, it is a slow process. Look around, you will find that there are many grown up people of your height. Wait for a couple of years more and see the change for yourself!

Totally. i'm [half] indian and i grew from 4'8 to 5'9 since the time i was 13 or 14 up til now [i'm 17]. So good luck!
