I feel like a naggy wife

My husband is so kind and he does help me but he gets on these stints where he just won’t. It’s been almost three weeks of me cooking dinner every single night and doing all the dishes. Usually whoever cooks gets off dish duty and we take turns. He hasn’t helped clean the house in forever. I had to ask him to clean his clutter off the counter last week and convince him it “couldn’t wait for a few days” because I needed the space to bake the next morning. I’m getting later in my pregnancy and it’s getting harder to stand up for long periods of time trying to cook and clean and bend over to scrub the dogs accidents he didn’t notice because he didn’t take the dog out for several hours. Nagging usually works but I’m sick of having to ask all the time to just help me out. It really makes me worried for when our baby gets here that I’m going to have to do everything on the weeks he just doesn’t feel like it. He had off all last week and somehow I still did everything after work every day. All he did was weed outside (which I helped with) and mow the lawn. The house gets dirty because we have pets. I expect the house to get cleaned on a regular basis but not be spotless perfect. I just feel really overwhelmed and alone right now and I’m just dreading sitting down and talking about it even if he never gets mad and talking usually sparks change (for awhile). I think his last two long relationships his partners spoiled him. I’m more 100/100. We both put full effort into providing since we both work and both pay the bills. I just need him onboard or I don’t know what I’m going to do.

Update: thank you ladies. I knew I needed to speak up but sometimes I need reassurance that I’m not completely out of line. I will do so soon. I feel like letting him have some slack this week with new job stress but this weekend we can actually sit down and talk since he’s always down to hear me out when I ask.
