Stay at home mom

So before I married my husband I was working when we married I was still working we moved and I quit my job, well I'm a stay at home wife and expecting our first, I cook and clean everyday and do whatever he needs me to do I take care of our dogs but I still always feel like I'm not contributing enough is this normal?! I was just so used to working, and making money, I want to work but lately I've been pretty sick.
