It's very strange! As for me, the milky path and the pregnancy path are very much connected, because well... pregnancy = breast lactation. As for the pregnancy itself... well, there's a rollback function, isn't there? So, the baby will essentially roll back as if it never happened. Alternatively, the pregnancy could be a mini-finale, with a picture and text about the happy life of the hero and his girlfriend, followed by a rollback button.
