Wake up every night at 3 since Fitbit Charge 2

[Lizster]

Hello there! 
I'm a new user since one week ago. I've worn my Fitbit every night since I got him.
It seems to me that I've been sleeping worse now than before. 
Every night at 3 I'm awake for no reason.
I've checked my settings but I could not find anything about notifications at night.
Could it be that my Fitbit vibrates in the middle of the night without me knowing it?
I did not receive any calls or messages during the night, so that could not be it.

Can anyone help me, because I'd still like to track my sleeping habits, but I'd like a good night's rest too.

Thank you very much!

Hi @Lizster I think the easiest way to test is for you to sleep tonight without your Fitbit on to see if you wake up at 3. There could be some other environmental thing happening that you aren't aware and you are now more aware of your waking because of your Fitbit. Give it a try tonight and report back.
