In brief: Frequently at first

Irregular menstrual cycles are extremely common in newly menstruating teen girls ages 11-14.
Around 14 to 15 years of age mother nature has the "ovulation factory" figured out and can consistently turn out a "new egg vehicle" monthly which regulates the periods if not on hormonal contraception.
