Baby controversy

Ok so, my husband and I are coming up on our first anniversary and have been trying the whole time. I have fertility problems and a big hole in my life where a baby belongs. I've lost 2 pregnancies that I know of in my life(both with my husband) and its a very sore topic. topicS wants a whole house full of kids and talks to my belly all the time just in case. I talk about baby stuff all the time, I'm a house wife and he told me to get a hobby, I chose baby research. But when I come to him with my new discoveries, ideas, questions and methods he gets angry and tells me kids are years away and he doesn't see why I want to talk about or speculate about them. The hobby was his idea and I could get pregnant any time, I don't understand what's going on, he just yells and shuts down or throws the fact another woman will probably need to carry out child in my face. I can't just not talk about babies, I've tried, I start to bubble over. What can I do to bridge the gap here?
