It might be a relatively unknown author who is just starting out in the world of fanfiction writing. They might have been inspired by other magical pregnancy storylines in different fandoms and decided to create their own version within the Harry Potter universe, using Hermione as the central character.
There could be many amateur fanfic authors out there who might have written such a story. It's hard to pinpoint just one. There are numerous fanfiction platforms where people with a creative streak and a love for the Harry Potter universe might have come up with this idea.
Well, it could involve a spell gone wrong during some magical experiment. Maybe a misfired charm that had unforeseen consequences on Hermione's body, leading to the pregnancy. The story might then focus on how she copes with this unexpected situation, both physically and emotionally.
Hermione had used Petrify All, a spell that bound the whole body, Forgetfulness All, a spell that altered part or all of a person's memory, and though she was not very good at it, she had used Food Charm (a spell for cooking food, not for making it appear). Harry Potter and the Prisoner of Azkaban wasn't enough. Everyone, please click to read the novel!
