Pregnant???

I just found out I am pregnant. I found out in an ER no less. I fell and thought I broke my wrist. The doctor wanted to test me just in case before I had an X-Ray. He came in and announced it like I was dying. We have been trying for 2 years. I was excited and pissed at the same time. I was happy that I was finally pregnant and I was pissed at the timing. I had planned a girls' weekend with my friend. It was to theme parks and such. We couldn't go to Six flags but I still got to do White Water and the Georgia Aquarium. I found out that I am old at 26. I could barely keep up with the little kids running around. We had fun but that is slightly off topic. I want to know why my husband who was excited about the prospect of children for a while is now all of a sudden freaked out. He refuses to even talk about it. I have to bring up the topic and then actually keep the conversation going almost by myself. I don't get it and it irritates the snot out of me!! I don't know what to do. He has to face it sooner or later but hopefully it would be sooner so he doesn't check himself out on me so I am not doing this by myself.
