The American College of Obstetricians and Gynecologists (ACOG) advises that when girls are between 13-15, they first see the gynecologist. Most of them will not need any exam. Still, the gynecologist will do a regular health checkup and talk to them about their development and diagnose any complication. This is a great way for a girl to develop a relationship with a gynecologist, and she can comfortably share the problem with a gynecologist in the future.
