- Cycles outside of the 24 – 35 day range that Ava is optimized for:
Please note that during your first cycle, Ava relies more heavily on the information you provided during onboarding about your average cycle length. If you need to edit the length of your average cycle, navigate to the calendar date of your first cycle on Ava, and use the + icon to add or remove your period.
- PCOS or other hormonal conditions:
Ava's algorithm has not been tested for conditions that can influence your hormone patterns such as PCOS or hypothalamic amenorrhea.
- Not enough data:
In order to work properly and to give you the most accurate predictions, Ava must be worn every night for a minimum of 4 hours and record at least 3 hours of sleep.
If this is your first cycle using Ava, sometimes not enough data has been gathered about your unique physiological pattern in order to make accurate predictions yet.
