While Ava has not been tested specifically for PCOS, the data that Ava provides may still be useful for you.
Ava's automatic fertility detection feature is only accurate for cycles between 24 – 35 days. If you have mild PCOS and your cycles are usually within this range, or if you are taking fertility meds to get within this range, Ava might work for you.
But even if you have more irregular cycles, you can actually "hack" the other data that Ava provides to figure out when you are fertile. Here's how:
In Ava's clinical study, we found that resting pulse rate rises between two and five days before ovulation. In cycles longer than 35 days, you would disregard Ava's built-in fertility prediction, and instead look for a rise in pulse rate, followed several days later by a rise in temperature.
One thing to note is that in PCOS cycles, the body may "attempt" to ovulate several times, but doesn't quite make it. When you see your resting pulse rate rise in Ava, it is showing a "potentially" fertile time. You can speculate that it was actually fertile if you see your temperature rise as well, signalling ovulation.
