Steps
Mark the first day of bleeding on a calendar or in the Tools tab.
Count from day 1 of one period to day 1 of the next. That is your cycle length.
After 3 months, average your cycle lengths and add it to your last date to predict the next.
Note mood, pain and flow too. Keep pads ready 2 days before.
