The Ava Fertility Tracker is a wearable, FDA-approved device that detects the fertility window in your menstrual cycle. It is synced to the Ava bracelet app on your mobile phone, where you can monitor the Ava chart.

At the moment, this device does not detect pregnancy. Rather, it is a convenient tool to maximize your chances of conceiving by detecting when you are most fertile.

How Does the Ava Bracelet Monitor Pregnancy?

The Ava bracelet can use your skin temperature and resting pulse rate to indicate that you may be pregnant. If you are not pregnant your temperature will return to normal, but if you are pregnant, your temperature may remain slightly elevated. You could also experience a rise in resting pulse rate. You would only know this if you continue to use the Ava chart when pregnant.

Can Ava Detect if You Didn’t Ovulate?

Yes. Here's how: If the Ava app detects a constant basal body temperature or an irregular cycle, it means you are not ovulating. Some women experience abnormal ovulation or "missing" ovulation for a month.

Does a Biphasic Pattern Mean Pregnancy?

No, a biphasic pattern means that you ovulated. Most women with ovulatory cycles have biphasic parameter patterns, and ovulation is a critical factor in getting pregnant.

Does Ava Tell You When to Take a Pregnancy Test?

The Ava device will not tell you when to take your pregnancy test - it monitors your fertility window to assist in falling pregnant.

Most doctors advise waiting until the first day of your missed period before taking a pregnancy test. This usually happens about two weeks after conception. Some tests, however, are more sensitive than others and can be performed earlier.


The Ava Fertility Tracker will alert you of your most fertile days to give you the best chance of falling pregnant. It can then be used as an early phase pregnancy monitoring service until you go for a pregnancy test.
