How come I am 15 and 4'7?!

Things that could cause it are malnutrition, endocrine system disorders, low confidence/self-esteem.
I'm not saying that you have any of these things, you might just be a late bloomer and jut up.. but you might have dwarfism so consult your doctor the next time you go.

When I was 15 I was 5'5 and 17 I was 5'7 1/2 Now I'm 5'9 (Been that way since I was 18) so since I was 15 I grew 4 inches. Basically your not done growing. Give it time hun. Although I hate beening tall personally :(

you might just be short. maybe you'll grow a few more inches but im guessing you'll only be about 5'2 when your an adult

One of my male friend is 5'2 when he's 15 ..

but at 18 He's 5'11 and joined the varsity...

now he's 6'1

Sleep...sLEEP...SLEEP....sleeep...

Are you a dude or a chick? Because dudes can shoot up pretty quick, as for girls... There's not much hope.
