Husband is not happy

I'm 29 and 9 weeks pregnant with my first. It was very unexpected, although we were planning on starting to try next year. My husband seems so unhappy and worried about having a baby. I'm over the initial shock and starting to get excited, and its very awkward talking about it with him bc he seems so freaked out. At first I was understanding, but it's starting to hurt my feelings! He has been very sweet and supportive of me otherwise, as i have been sick and tired and very moody! Did anyone else go through this?? Did your guy come around?? Please be nice, I'm hormonal ;)
