Advice on getting husband to help

Guys, can anyone shed some light?! My husband will not do his part around the house at all! Yes he works full time, I stay at home with our 20 month old and work a few days a month (albeit it’s 14 hour days when I do work bc I’m a nurse), we are building a house and that’s a lot of responsibility on both of us, I am 15 weeks pregnant with our second. We are both busy and tired. But as usual, I am constantly taking care of our toddler and he gets lots of alone time and breaks. He goes deer hunting in the evening, he gets to go to the new house and look around without the baby all the time, every time I go out there I’m basically chasing the baby to make sure she doesn’t get hurt out there, his parents live really close and help him whenever he asks, my parents don’t live as close, and I just ask him to do one or two things here or there whenever I am working and don’t get home until 8 pm and he just literally won’t. He says he will try but nothing ever changes. He tells me that I just don’t like being a stay at home mom bc I am complaining by apparently asking him to help.

Example: i worked today, got home at 8, he got off work at 1 pm, went to the new house to look at the progress, his mom was watching the baby, then he went straight to his parents house where his mom does everything, hung out there and then went hunting from 4 until dark. I called him to ask him some questions about the cabinet measurements bc the cabinet maker was asking me while I was working, he bit my head off bc he was trying to get dressed to hunt and was running out of time to get on his stand, after he finished hunting, he went back to his parents, ate dinner there (whatever his mom made), then brought the baby home about 7:15 and just hung out until I got home. He bathed the baby and I read her books and put her to bed. When I left her room I asked if he could just help out a little bit on the days I work. Like fold a load or even put some clothes on the wash, anything to help me get ahead the next day when I’m off. He said “yeah I’ll try”, but what about the days I come home and you haven’t done anything....and I’m like uhh ok really?? I proceeded to put some clothes on to wash and move the wet ones over. I don’t understand why he doesn’t want to help me. I’ve been gone since 5:30 am and I’m pregnant and tired. He will stay up watching to until 12 midnight. I’m literally to the point where I don’t want to do anything for him anymore. Cook for him, clean for him, do any of his laundry, i want to use a different bathroom and keep the one I use clean, km so sick of not feeling appreciated for how much I do and for him never lifting a finger in this house. Like what does he expect will happen when baby number 2 gets here?!

Someone tell me what to do!
