Dear different,

What you're experiencing is very common! Puberty doesn't happen all at once — it happens in stages. So a girl or guy may show some signs of puberty at an early age (like breasts beginning to grow or a voice that's starting to crack), but may not show other signs of puberty until she or he is much older (like getting a period or growing facial hair). Believe it or not, it can take up to 20 years of age for all changes to take place. If it's something you're really concerned about, you might want to discuss it with your clinician or family doctor.

Hope this information helps!

Take care,
