Anyone else working a physical job while pregnant?

So this is my first pregnancy after 5years of TTC. I want everything to go smoothly. I’m 6+4. I work as a dietary aide in a nursing home. Only 26hrs a week, but for the past week after a shift my back is so sore....like it’s going to give out on me. I begin cramping too.

I was talking to my husband about going to 20hrs a week because of it. His response “maybe I’ll drop a shift too”. I feel like he’s not being understanding/supportive. We’ve saved up so much through the years that if I dropped a shift it would not hurt us financially even long term.

I feel like I’m pushing my body too hard already. If anything happens with this pregnancy I would probably quit all together and give up. I want this baby so badly. If you’re working a physical job how are you handling things? Is your husband supportive?
