cravings or desires?

cindy remarked yesterday how she found it odd that she requested a chocolate cake for her office birthday party. she doesn't really like chocolate. she noted, in fact, that she had a bit of a craving for chocolate no matter its form - cake, candy, whatever. could this be the first pregnancy craving? do cravings happen this early in pregnancy? i don't know - but i do know that i will attribute just about any change in cindy's behavior right now to pregnancy, and that is totally cool. as she mentioned in the last post, i'm loving this!
