When you change your mode from Clue Pregnancy to Clue Postpartum or Clue Period Tracking, your Cycle View will be empty until you track your first period.
After pregnancy, the return of someone’s period depends on various factors such as breastfeeding/chestfeeding and can vary greatly between individuals. Some people may get their first period after a few weeks, meanwhile for others it can take more than a year. Because of this variability, Clue cannot calculate an accurate prediction for when your next period will start.
As soon as you track your first period, the Cycle View will show your upcoming cycle predictions.
