Feeling blue

I'm having a lot of days of not feeling like the love of my husbands life. He is a wonderful husband and is so excited about our baby but between bills, preparing for baby, friends and just being so exhausted from work I feel like I'm just the human incubator. I don't really want sex right now because it's just uncomfortable but I miss intimacy. Any tips? I feel like it's become so much about all the hard stuff with raising a child and not about the beauty of it. I mean this is my first pregnancy. What do I do?
