Can't keep up with house!

I am only 8 weeks prego and I cannot seem to keep up with cleaning my house! I am usually OCD about things being clean and put away... And lately I've been so tired and nauseous I just don't care. Don't want to complain to my hubby because he has been doing everything for me minus the house work... But I feel like I'm going a bit crazy! Any advice from other mamas? How am I going to keep up with a baby here if I cannot even do it now?!
