There's a fanfiction where Chuck is actually a time - traveling entity in the Supernatural world. This one is really interesting as it plays with the concept of time and how Chuck's actions across different eras affect the present - day storylines of Sam and Dean.

Well, 'Sam's Unplanned Path' is a great one too. It not only focuses on Sam's physical changes during pregnancy but also on his mental state. The author does a wonderful job of showing how Sam deals with the fear, excitement, and all the mixed emotions that come with being pregnant in a world full of the supernatural.
