Ava gives you two different types of information:

1. Physiological data from when you were sleeping
2. An algorithmic prediction of your fertile window and ovulation based on the physiological data 

The algorithmic prediction was created based on cycles that are between 24 – 35 days. It is not designed to detect fertility for women with irregular cycles, PCOS, recently postpartum, or who are breastfeeding. If you are in any of these situations, you should not rely on Ava's fertility detection feature because it may not be accurate for you. You may, however, find the physiological data that Ava provides to be useful in tracking your fertility. 

In our clinical study, we found that resting pulse rate tends to rise a few days before ovulation. We also found that temperature rises after ovulation. You could look for these types of patterns in your Ava data to try to identify your fertile window and ovulation date by yourself.
