while using Glow, I also purchased the Ava bracelet for closer monitoring and can I tell you, this thing is awesome!!!! it takes about two cycles for it to really know you but even after my first cycles, it was on point with Glow. I still use both because Glow gives me a lot of information that is important and I input things like meds and weight which I want to track. With Ava, your temperature and heart rate are entered automatically so you don't have to worry about trying to remembering to check your temp at the same time everyday. I'm giving a referral link here which gives you $20 off. Believe me, it's so worth it. And you can keep using it while pregnant too 😁
