Scanty or infrequent menstruation



Menstrual periods that happen less often than the average 28-day cycle.


Some lifestyle factors can affect having periods. These include too much exercise, low body weight and stress. So try for balance in work, play and rest.

When to make a doctor's appointment

See a healthcare professional if:

  • At least three menstrual periods in a row are missed.
  • Age 15 or older and never had a menstrual period.
