I logged a period before CD 16 but the algorithm did not start a new cycle - why?
The algorithm will only start a new cycle with a period entry if the last cycle was longer than 15 days.
This means that if you add a period before Cycle Day 16 (CD16), the app will not start a new cycle.
Cycles that are shorter than 16 days are considered irregular cycles. To learn more about irregular cycles and what could cause them, please follow this link. If you feel any reason for concern about a short cycle, please contact your healthcare professional.
How to log cycles that are shorter than 16 days
If you get your period before CD16, we recommend that you log this as ‘Spotting’. You can also use the notes section in the ‘Add data’ page to describe the bleeding if you would like to.
Once you reach CD16, you can log any bleeding you get that day or the following days as ‘Period’. Doing this will allow you to keep track of the bleeding, and the algorithm will adjust accordingly and start a new cycle from the period entry on CD16.
