Early am wake ups, anyone?!

Kerri
I don't really have a problem falling asleep, tossing and turning etc. but for the past week or so I wake up at 4 am almost every day! I am 27 weeks and really can't complain as I've been well rested not sick not huge/uncomfortable overall - just wondering if anyone else has anything like this happening?! I think I'm just going to start embracing it because I need to get up by 6 for work and by the time I fall back to sleep when I do get up im exhausted and end up staying in bed til 6:30 haha.
