A Simple Period Diary to Spot Your Pattern
Writing the start date, flow, mood and sleep in a small notebook. Useful at the doctor's if cycles turn irregular.

A notebook that helps at the clinic
Many women cannot remember the exact dates when the doctor asks. A small notebook in which you write the start date, how heavy the flow is, how you slept and how you felt for a few months quickly shows your own pattern. It does not treat anything, but it makes a doctor's visit far more useful.
Write the first day of bleeding, the number of days, the flow (light, medium, heavy), pain, mood and sleep. See a doctor if cycles are very irregular, shorter than 21 or longer than 35 days, very heavy, very painful, missed for three months without pregnancy, or you bleed between periods.
