he said he doesnt want children anymore

We've lost our daughter when I was 32 weeks pregnant, its been 10 weeks since then. It feels like everything went by so slowly but so fast at the same time. She would've been due 4 days ago now and I feel awful. My husband and I had huge problems in the beginning because I just couldnt even look at him without breaking down. We somehow managed to be okay with each other again, I still feel extremely uncomfortable and I dont think this will ever end but like I feel so naked and empty. We have two other kids I'm keeping up with. They're a good distraction but a horrible reminder at the same time and I feel like I'm the most awful mother and wife ever.
We didnt have sex for like 4-5 months now, I know he's fustrated but I just dont feel ready at all yet.
I asked him if we could just try for a new baby and he said its way too early. I dont want to push him but I think he doesnt know how I feel and he told me we should wait and I should at least start going to uni because thats what I've been planning my whole life.
I dont know what to do I somehow feel ready to have a baby because I just want a new baby but at the same time I just feel so stressed and I'd be way too scared to lose my baby again.
I don't know if this group is okay or not but I feel like you guys could maybe know how I feel?
