I don't really know how to reply to your question about "Who's your Daddy"
But question one:
Some people can be different when pregnant. It just depends on the body you know ? They'll be a slight tiny pudge or some people will show a belly early on during the pregnancy.
[Ive read two books were they looked skinny af]
Question two:
Mpregs or omegaverse world depending on the author really. They'll either have a C section operation or they will give birth outta the ass..I've read two where they'll give birth through the ass. But the rest have been a C section operation.
Question three:
You can have sex while pregnant. Sometimes if you are trying to get that baby outta there doctors will recommend sex.
It's a mpreg just another fanfiction like how there's furry fans you know?
Hopefully this helped ~

I have a theory that all the women in this world got on a rocket ship and flew away to start a women-only planet, leaving the men to fend for themselves.
Honestly their prob rare bc they are either locked up or disguised as boys fr and maybe, hopefully have their own little building to themselves. (ーー;
