How would you deal with this?

So I am due Feb 15th. I'm 5 weeks and I am super excited to be having my first. My husband and are are over the moon. We told a few friends because we couldn't hold in the excitement. But ever since we told some people I no longer feel like I have any other personality trait then pregnant. They won't talk to me about work, the news, movies, books, etc. It is all baby all the time. Even going as far as calling everything I think sounds good to eat a pregnancy craving. The worse part of all of this for me is these people have kids they have been through this. How would you guys deal with people no longer treating you like a person?
