What are the signs of puberty for girls?

Puberty is experienced between the ages of 8 - 13 in girls. During this time girls bodies become rounder (hips, thighs, and buttocks) and their breasts grow. Around this time, girls will also begin menstruating. Once a girl is going through puberty, she can get pregnant.

Menstruation or periods happens monthly (menstrual cycle), and can last between 3 -7 days. When a girl/woman menstruates, the body sheds the lining of the uterus. The blood flows from the uterus through the small opening in the cervix and passes out of the body through the vagina. Periods may come irregularly at first and may cause cramps (abdominal pains).
