Need a little advice.

Lately I've felt my SO isn't excited about our pregnancy. He never talks about it, anytime I mention it its like it goes in one ear and out the other. I brought it up to him and he swears he's excited but hearing it and seeing it are two different things. I asked if he thought I should set up an appointment for a 3d ultrasound at 14 weeks and he said he doesn't really care that were just gonna see it on a regular ultrasound and that it's a waste of money. His argument is that he's stressed because I quit my job due to high risk complications and my job consisted of standing on my feet 100% of the 9 hour shift with no breaks not even to eat. Also I had been put in dangerous situations many times while working there and earning a paycheck is not worth risking my child and I's life. So I'm currently trying to find another job where it's more safe, and my high risk complications don't restrict me from work. He understands that but stressing when we have plenty of income from just him and all of the ends are met I just don't understand how that has an impact on showing happiness. He used to cry with me during our long struggle of TTC and now that I'm pregnant it's like none of that heartache never happened. I just want to feel like he cares... we got in a big argument before bed about it and now he's asleep and we won't be able to talk this out until after 5 tomorrow when he gets off work. I'm just hurt.. I feel like he feels I'm making excuses just to not work. I'm walking around with a heart monitor strapped to my chest for heart pallapitations which is part of the reason I can't work! I just needed to get this out.
