Just curious what does it mean if normally I'm 95 and then last night it was 91 lower then it's been before. I'm not worried just curious is that from working out so much this week maybe I'm super tired so it was lower? Or is it random.. There isn't much information about what it means if your low

This help page explains the Fitbit SpO2/blood oxygen readings (<-- click link).
Based on the above article, it looks like your SpO2 reading might have been lower due to your activity and being tired. You might need a rest or lower activity day for recovery.
