Ava bracelet while pregnant

Does anyone else use an ava bracelet while pregnant? If so can you tell me your experience with it?

The last 4 nights i have gotten “insufficient data” and except for one night I’m considering an outlier because it said i only slept for 3 hrs which i know is wrong. So basically for four days i don’t have any good data... I’m 5w2d today and this is very frustrating to me. I know I’m wearing it properly because i didn’t have this issue before i got pregnant.
