Hubby doesn't understand

Me and my hubby just haven't been getting along since I've gotten pregnant, granted I know I'm a basket case but he just doesn't understand that I don't mean it towards him in anyway I've tried talking to him about it but he still doesn't get it! It's really upsetting me because he pretty much told me today if I was going to keep acting so moody that he was just going to be done talking to me and just go on about his day like I'm not even there, it's really starting to make me feel like he doesn't care... We love each other and have been together for the past 7 years! And this isn't like us at all!! I just don't know what to do!!!
