How to get hubby to understand I’m physically tired!?

So I only work 4 days a week, but my hrs are 2pm-9. Then very next day 7am-3pm. All my shifts are back to back. I’m trying so hard to hang in there. Most of my weight is carried in my legs. I have vericose veins that are starting to cause problems. When I get home after my 7-3 shift I’m literally crawling on the floor to go to the toilet bc my legs are in so much pain. It feels like my bones have shattered and my hips are peeling off then I get pressure in my pelvis like baby is going to fall right out. It’s our first child (5 years of TTC) and I’m nervous and scared. My job requires LOTS of bending and lifting, and is fast paced. Sometimes I struggle to have a break. I’m getting slower too I’ve been finishing an hour late which I don’t get paid for.

I explained this to my hubby and his advice was, “you need to exercise more. Try going to the gym”. Thing is I already feel like I’m over working my body.

We’re not financially struggling, but I think he’s anxious to see a drop in our combined income sooner than expected. I plan on working until 35 weeks (27 weeks now) but I’m already struggling so much and I don’t want to disappoint my husband. I was thinking of reducing my hrs or asking my boss to swap a couple of my shifts (to have a bit more rest in between shifts) around as so many people are on leave at the moment and into December. I spoke to my doctor about this and he said I should reduce hrs if my legs are getting worse, just wish my husband was supportive of the idea and had my back.
