The menstrual cycle is a recurring cycle in which the lining of the uterus thickens to prepare for the possibility of pregnancy and then sheds if pregnancy doesn't occur (source). The shedding of the uterine lining is the bleeding phase of the cycle, also known as the period (source).
Your menstrual cycle starts on the first day of your period and ends the day before your next period (source).
Track your period in the Fitbit app to learn about your typical period length, estimated fertile window and ovulation day, and other information related to your cycle. Log your periods for more accurate predictions and greater insight into menstrual patterns. For instructions on how to log a period or details, refer to How do I use the Fitbit app to track my period?

The predictions for your period, fertile window, and cycle phases are estimated with an algorithm that includes the period and cycle length information you provide. It’s also affected by ovulation test results that you log.
If you don’t provide some of the information about your cycle, Fitbit uses a 28-day cycle and 5-day period as a starting point for estimations. Your fertile window is always shown as 7 days in the Fitbit app, which includes the 5 days before ovulation, the day of ovulation, and the day after ovulation.
Period and fertile window predictions become more personalized as you log your period consistently.
You can edit the average cycle length and period length you provided during setup. However, these settings only affect your initial predictions. For more information, refer to How do I use the Fitbit app to track my period?
Important: Cycle phases are currently available on the Fitbit Mobile app for all Android users.
The Cycle phases feature offers evidence-based insights into nutrition, mental well-being, sleep, and activity during each phase of the menstrual cycle. These insights provide general guidance and understanding of physical changes during the menstrual cycle. For personalized advice and treatment plans, please consult with a qualified healthcare professional.
- Period: The phase that begins on the first day of your logged or predicted menstrual bleeding. Although it's part of the follicular phase, it's emphasized due to the experience of menstruation.
- Follicular: The phase that begins after your period ends and continues until the day before your predicted or logged ovulation. The last 5 days of the follicular phase are known as the fertile window, a time when pregnancy is more likely. Fertile windows typically span 6 days, but in Fitbit, it spans 7 days to account for variations in the time of day that ovulation occurs (source).
- Ovulation: The phase that marks the release of a mature egg from the ovary. Due to its importance in the menstrual cycle, ovulation is highlighted as a separate phase.
- Luteal: The phase that begins after ovulation and ends the day before your premenstrual phase. This hormonal shift leads to distinct physical changes.
- Premenstrual: The phase that occurs in the 5 days leading up to your predicted or logged period. Although it's part of the luteal phase, it's marked by a range of physical and emotional symptoms.
Your menstrual health data helps you track your patterns and notice variations. Your menstrual cycle can be influenced by various factors, such as hormonal birth control, pregnancy, and other health conditions.
While you use hormonal birth control, you can use the menstrual health tracking feature to track your cycle and details to help you recognize patterns. You may want to turn off predictions in the menstrual health settings and manually log your periods. For more information, refer to How do I use the Fitbit app to track my period?
