How you prepare

By Mayo Clinic Staff

Tracking your menstrual history doesn't require special preparation. However, if you want to use the rhythm method for birth control, consult your health care provider first if:

  • You recently had your first period, gave birth, or stopped taking birth control pills or other hormonal contraceptives
  • You're breast-feeding
  • You're approaching menopause
  • You have irregular menstrual cycles
