Why is my (fat) female chinchilla laying partially on her side? is she pregnant?

Yes. Most likley she is! Congratz!

I would see a vet right away!

Probably. Your vet can help you confirm this and help make sure things go well.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
