So I haven't been wearing mine as often as I used to. For the past week months I've only been wearing while sleeping. My average rest heart rate is usually around 53 and goes up to 56 when my period comes. (This is my past 2 months while sleeping not when I wore it all day but even then it was the same) I'm currently 9dpo and the past 3 days my rest heart rate has shot up to 59. I noticed my heart rate while I'm sleeping is now what my old resting heart rate was at 53/56 and when I wake up in notice my heart rate instantly sky rockets. I wore it for a few hours before bed last night to see what it is while I'm just relaxing watching TV and it was in the high 60s and 70s. I wanted to ask you mom's and women who are pregnant that wore Fitbits when they got their bfp and if they noticed changes like this when they found out they were pregnant. Thanks!
