How do I log the start/end of my period or edit a logged one?

To log the start of your period, tap the Log Period button on the main screen > Check if the marked days are correct > select Save. The selected days will carry forward to your next cycles.

The end of your period will be logged automatically according to the period length specified in Menu (your avatar in the top left corner) > Cycle and ovulation.

If you want to edit your period dates or add past periods, tap the Calendar icon in the top right corner > Edit period dates > Mark the required dates > Save.
