Hi, may I answer your health queries right now ? Please type your query here...i m 16 years old. i got my period when i was 12, and i m still irregular. i m 4 feet 11 inches, and i ve never had a growth spurt, my doctor says my knees are pretty much done growing and i ll prolly never have a growth spurt. i weigh approximately 98 lbs and i ve been 98 lbs for a couple years. my boobs aren t getting any bigger and my face is hasn t really changed. the only thing that could possibly indicate that i m a sophomore in highschool is that i have a bit of acne (a pimple or two) and body hair (that i shave off). as far as the rest of the world can see, i have the body of a 12 year old. my point is... WHY AREN T I GROWING?
