My daughter (almost 16 years old) is only 5'1. A few months ago, we had an xray done of her hands, and it said her growth plates were closed. Does that mean she is the height she is? She really would like to grown a couple more inches. I am 5'2 and her dad is 5'11. She went through puberty early (she got her first period when she was 10), but she doesn't have much breast developmentat all (she wears a 32 A and that's still a little big on her). Also, she hasn't had her period in almost a year now. She has been tested for fibroids, PCOS, and pituitary tumor. I am concerned that the doctors are missing something. They tested her thyroid and that came back normal as well. What could be going on?
