Rant about house work

Before I got pregnant I done about 80% that include all the dinners laundry grocery shopping and most of the cleaning. We also got a puppy literally 3 weeks before I found out I was pregnant. I work the night shift and got around 5 hours of sleep a day, I was able to function on it. Now that I'm pregnant I feel like I've ran a marathon after I've finished house work and such before I even get to work. So I've just kinda stopped doing the things I used to do because I couldn't stay awake at work and napping before work ended up trumping house work. My SO is livid I've stopped helping out which is understandable. It just made me realize how awful it had gotten he will re wear thilfy work cloths for days so he doesn't have to do laundry compared to me doing it every other day. He never let's the puppy out but will wake me up to come pick up poop. It's made me more unmotivated than ever as awful and possibly slobbish as it sounds. He's a great man but I think I unknowingly babied him.
