Oestrogen and progesterone are the two main hormones responsible for the changes in girls.
Here are some of the changes you can expect to experience as you go through puberty.
1. Hips widen
As your body grows, your hips widen in preparation for you to carry a baby in the future.
2. Breasts start to grow
The oestrogen your body is producing causes your breasts to grow. You might feel itchy or uncomfortable when this happens, but it’s completely normal.
3. Changes in your vagina
Your vagina and vulva will grow bigger, and you’ll start to produce a clear or white liquid (vaginal discharge) – this is normal and is how your vagina keeps clean and healthy.
If the discharge is yellow, smells or your vagina feels itchy, you should see your doctor as you might have an infection. If you notice more discharge, it might be a sign that your period is going to start soon.
4. Periods (menstruation)
Your periods will start at some point during puberty. You might get period pains in the lead-up to your period and during it too.
Period pains can usually be treated at home, and you shouldn’t need to take time off school. Having a warm bath or shower, or placing a covered hot water bottle on your tummy, can also help.
You may not feel like exercising when you have period pains, but gentle exercise can actually help, so maybe try going for a walk.
