My reading of this thread was interrupted by a call from my extremely pregnant wife, who just informed me that she'd emptied out both bedrooms and the storage closet, which had been full of a waist-high, person-long stack of boxes, loaded them into her truck, and was in the process of taking them to our new place.
So unless your character concept is "person who gets her magical power by punching herself in the stomach over and over again", your fantasy pregnancy should probably be as painless as you'd like it to be, aside from flavor-text about a strange craving for picked shrieker or a tendency to get weepy every time you use Great Cleave.
