What does dreaming of being unhappily pregnant mean?

I had a dream last night that I was telling my husband that I was pregnant. I wasn't very happy about it in the dream, more a feeling of being resigned to the fact. He appeared fairly grim at the news as well.

That was the extent of the dream. There was no conversation. My husband and I are facing some difficult decisions in our future, and while I wouldn't be thrilled to find out I'm pregnant at this point. I am inclined to think that the dream isn't really about pregnancy at all, but would like other opinions.
