Sleeping like a baby now.

Is anyone else having the best sleep of their life? I'm 31 weeks pregnant and for the past week or so I have been sleeping so well and so much lol today I struggled to actually keep my eyes open despite sleeping for more than 12 hours. All my bloods are normal so I know I'm not lacking any vitamins. And I'm not a very active person during the day so exhaustion isn't the reason to my good sleep lol. Just thought I'd share something a little positive on here... don't know long it will last but Yh  😊
