My daughter is 11 years old. She's 4 ft 6 inches and 59 lb. She has not develop breasts or have pubic hair. However, this mortning she had a light redish discharge in her underwear. Could she be starting her period? Is this possible with her stature? Or should I be taking her to the doctors right away? She is being watched carefully by her doctor because of her lack of growth and lack of weight gain.
