Hey there Roksi23,
It is hard to answer your question right now since all birth scenes in the original game happen within the same animation sequence, as you see with the Wharf Roach.
I don’t think I would make pregnancy a status effect, but I would like to add it as a lasting detail, where you would carry a bigger belly for a while and have the birth scene later, but since there are no original CGs for this it is hard to say right now how and if I’m going to proceed with such a feature after version 1.0.
