There will be some pregnancy in one, possibly two, of the endings. There is in-game pregnancy planned for Falling Stars 2 but I'm not sure that game will be happening, unfortunately.
Sadly, it's due to a general lack of interest and support for the original game. But I hope all the separate endings I have planned for this one will wrap up the story in a very satisfactory way for everyone while leaving things open for the possible sequels. I'm not fully ruling out Falling Stars 2 and 3, as I have the base stories written for them but it seems unlikely at this point.
