What should I do?

I am 24 weeks as of yesterday and the past month or two my husband has been slacking off helping with chores. At first he would do a lot when I was too tired or sick to move. Now I am constantly cooking, and cleaning while he sits and plays on his phone or watches TV. I am a full time college student and although this semester is over I will be starting in the summer so it's not like I don't do anything, not to mention I also have a 8 year old and 2 year old. Yesterday my husband told me my car needed vacuumed, so I grabbed the shop vac and pulled my car into the garage and began to vacuum it, at first I thought he would help but instead he continued to sit. I understand it's good to stay active during pregnancy but while I was moving around in my SUV I kept getting sharp pains and my back was cramping. I am worried I am doing too much and he's not caring as much anymore. I stood on my feet for 3.5 hours cooking, chopping vegetables then washing dishes as they got dirty all while my husband sat on the couch watching tv. I feel like it should be his instinct to get up and help his pregnant wife. So I'm asking my fellow pregnant <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> ladies, should I continue to do these things? Because If I don't clean and cook and all other things I've been doing then he won't do it.
