Is Mona's pregnancy not implemented, or bugged? She'll happily pump the PC full of eggs if asked (or on her own if you let her) but they all just dissipate after a while and the status screen insists your orifices are devoid of any content.
Yea, I don't think there is a pregnancy for that right now because it used to only be a loss scene. I will make a note, and see if I can add it in a future update
