We recommend that you wear Ava every night during your whole cycle for both follicular and luteal phases, as the physiological changes that occur during your entire cycle are important to improving the accuracy for your fertile window and ovulation predictions.

Of course it can happen where you might have forgotten to wear the Ava - if this happens, please follow the do's and don'ts below to make sure your Ava is charged properly.

Missing several nights can impact the quality of Ava's predictions which is why we do recommend that the Ava be worn every night.
