Your body during puberty
Hormones
When you reach puberty, you experience changes. Your body does, but so does the way you feel. All of these changes are driven by hormones. Hormones are a kind of control mechanism in your body. They regulate how you look, how you feel and how you behave.
Breasts
Breasts start to develop somewhere between the ages of 8 and 13. Rapidly for some, more slowly for others.
Labia
The inner labia grow as well. They become more elongated than the outer labia.
Hair
Hair grows on and around your labia. Fine hair at first, which later becomes thicker and curlier. You grow underarm hair as well.
Growth spurt
A lot of girls have a growth spurt around their 12th year: suddenly they grow much taller. Girls often start getting taller before boys do. A growth spurt like this is often followed by your first period. Your figure changes as well. Your hips, buttocks and thighs become more rounded during puberty.
Periods
Somewhere between the ages of 9 and 16, you have your first period. Most girls have their first period at the age of 12.
Puberty
Breasts
You develop breasts during puberty. This could start in a girl of 8, but also in a girl of 14. Age varies for all girls
