Ava Bracelet

I just started using Ava almost two months ago. I have PCOS so my periods are pretty unpredictable. This month, it predicted my start date and was almost accurate! On my predicted start date, I started spotting. I ended up starting one day after. This morning, I synced my bracelet and got an update that my fertile window starts today! My glow app predicts my start to be in 8 days... that’s a huge window! I’m hoping it’s accurate! Anyone else using the Ava bracelet? Do you love it??
