I would like to do a mystical pregnancy for a story, with the female as the main character. One of the gods from the world pantheon wishes to be reincarnated into the physical realm in order to experience what it is like to be human. Due to ancient laws made eons ago, gods cannot enter the realm in their true form. He proposes the woman allow herself to be used as a conduit to be born into the mortal world in exchange for power, which she accepts.
I would like to write this from the mother's perspective, and differentiate it from a normal birth. How can i write this in a way to make it unique?
