So I just got an advert on FB regarding a wristband that tracks your heart rate at night to monitor your fertility (yes I obviously research about fertility too much if FB is on to me). It is called Ava, and I am really kind of intrigued by it. Has anyone tried it? Is tracking your heartbeat Hocus pocus, or awesome weird science like Ferning?
Re: Heartbeat Tracking
As far as I know the heart rate increase is an early sign of pregnancy and I've heard anecdotes about women finding out they are pregnant because their Fitbit picked up on heart rate changes.
