Is it dangerous if a girl does not mature til1 15 years old?
Every person on earth is a bit different. Some are tall and some are short, some have light skin and some have dark skin. In the same way, every person has his or her own way and time to grow up. Remember that there is nothing wrong with maturing early or maturing late. But yes, if a girl does not get her periods even when she has crossed 16 years its good to consult a doctor.
