I’ve given birth recently but not breastfeeding. Would I be able to start using the Ava right away again?

The answer is: it depends. Here's why.

Ava gives you two different types of information:
  1. Data collected while you sleep about your temperature, resting pulse rate, physiological stress, and sleep.
     
  2. A fertile window and ovulation prediction based on your physiological data.
     
The fertility prediction is only accurate for cycles that are between 24 – 35 days. If your cycle hasn't returned yet, Ava's algorithm won't be able to provide you with predictions for a fertile window or ovulation.

However, by looking closely at your temperature and pulse rate data, you may be able to spot signs of ovulation on your own. In our clinical studies, we found that resting pulse rate starts to rise in the days leading up to ovulation. We also saw that temperature rises after ovulation. If you see a rise in resting pulse rate, followed several days later by a rise in temperature, that's a strong indication that you may have ovulated.

Even if you are not breastfeeding, you may still be getting up often at night to feed your baby. Please keep in mind that Ava needs to be worn at least 4 hours per night with at least 3 hours of sleep recorded in order to get an accurate reading.
