Anyone else have baby fever??

I don't know what has gotten into me but I have a severe case of baby fever! I am already blessed with 3 healthy children, but I have been very emotional over wanting one more. I'm going on three months of this feeling and it just seems to be getting worse. My so and I always talked about having 4 but after a mc and then bleeding quite a bit after labor with my last, he's not on board. I understand his concerns, but I feel ready for another. Anyone else experiencing "baby fever"?
