How can I track my menstrual cycle?

To find out what's normal for you, start keeping a record of your menstrual cycle on a calendar. Begin by tracking your start date every month for several months in a row to identify the regularity of your periods.

If you're concerned about your periods, then also make note of the following every month:

• End date. How long does your period typically last? Is it longer or shorter than usual?
• Flow. Record the heaviness of your flow. Does it seem lighter or heavier than usual? How often do you need to change your sanitary protection? Have you passed any blood clots?
• Abnormal bleeding. Are you bleeding in between periods?
• Pain. Describe any pain associated with your period. Does the pain feel worse than usual?
• Other changes. Have you experienced any changes in mood or behavior? Did anything new happen around the time of change in your periods?
