Hormones getting the best of me?

So I don't really know where to post this so here goes.... I am now 18 weeks pregnant and since I got pregnant my husband has not been paying a lot of attention to me. I feel very neglected since we found out I am expecting, I always thought my husband will be more excited, loving and caring when I am pregnant. Is this just my hormones screwing with me or do I expect too much? At the moment I just feel like a woman carrying his child, I don't feel like his wife.
