What if your 15 and you still have the body of a little girl ?

Confusing descriptin: People come in various shapes and sizes and your description is vague. Any female with no nipple enlargement by 11 or menses by age 15 should see a doctor for a full evaluation. If you have had both but remain petite, you may still have need for an evaluation but the urgency for scheduling this is less pressing,you may just be a small person.
