Why don't i have breasts?

Answer 1

I'm going to assume you are a girl.

When boobs start growing it is a sign of puberty. For most girls they start changing around 10 or 11 years old, but anytime between 8 and 15 is fine.

First the area around the nipple (called the areola) swells and darkens. A breast bud develops underneath as the boobs start to grow. Tiny glands looking like bumps appear on the areola.

Breast may look like cones for a bit but they round out after a year or so. They may hurt or tingle a bit whilst they're growing. Most breasts reach their full potential at 18.

Answer 2

Different parts of your body develop at different times. Now that you have had your first period, your body with begin to change.

Remember, it doesn't happen overnight. Your breasts will already have started to grow, but you will not have noticed yet.
