Around age 12, underarm hair begins to appear in girls. Somewhere between 10 and 16.5, menstruation commences, note University of Virginia health experts.
Migraines

Mayo Clinic doctors point out that between the ages of 4 and 7 migraines are more common in boys than girls. Once puberty starts, though, females are three times more likely than males to suffer from migraines. This coincides with the onset of menstruation, which often triggers migraines.
