Oh, yeah, I forgot to report this because, personally, I'm not into pregnant content: Ginny being pregnant does not seem to affect her schedule at all, in fact, I never got any sort of scene of her announcing that she's giving birth or anything. I got her pregnant twice and didn't even see the baby anywhere.
More over, at literally any time you can find a version of her pregnant on the hospital, floating above the bed. It's interactable and you can fuck her there regardless of passion. I am also assuming it's because of this sex-having that she got pregnant the first time, because I wasnt at a point where the MC could have actual sex with her when the pregnancy happened.
So yeah, Ginny's pregnancy feature is pretty buggy.
