Here's a question... not including the girls who can get pregnant now before Act 3, if you added that for other girls later would they have to get preggers before Act 3? Basically would you have to restart the game for any girls who can't get pregnant at the moment, if you added it for them?

Most of the side girls will be able to get pregnant in Act Two and probably Act Three as well once that point is reached.
That will happen when the game enters beta, though, and everyone will be strongly encouraged to start the game again once the beta period nears completion/gold release is done as the entire game will be getting a facelift and a code refurbishment just to make everything as shiny as possible before I declare it done :)
