12w and still exhausted!

Christina
I'm 12w2d today. I had some scheduled days off work this week and I'd planned to do all these things- like go through old clothes to donate, declutter and just catch up on housework. Well it's day 2 of being off and I haven't done anything! I'm just so tired, and I lack motivation to do anything. Am I the only one? I thought I would start getting some energy back by now?
