I’m 15 years old and I don’t see any development in my breasts. Should I go to the doctor?

They're really sore todayThe timing of physical changes during puberty in both boys and girls can vary quite a bit and still be normal. However, almost all girls will notice that their breasts are developing by the age 13.  So make an appointment with your primary care provider for a check-up and a discussion of why your development is late.
