I try to avoid committing to future stuff happening until I know it for a fact, but the current plan is to have actual pregnancy content at some point in the game. It won't happen in the coming v0.6 update, that's all I know right now.I don't think there is any pregnancy (text) content in the game so far. It's something that might come into play in the future, but I seem to remember that Alcahest wasn't even sure it would ever feature.
I'm not sure this game should have the pregnancy tag right now. Maybe better to delete the tag?
