Lack of affection from my wife

So guys, have any of you experienced this as well? Lately, any affection from my wife has dropped significantly since we found out that she was pregnant. I'm not just talking about sex; I'm talking about simple things like gentle touches or hugs and cuddling too. She's in her eighth week, and I know she doesn't really want sex, which I'm fine with, but it's hard to handle that part even more when I don't even get the simple, non-sexual things either. It seems that she cuddles with our dog or cat more than with me. Any advice?
