Once you have your characters and plot, start writing. Don't worry too much about grammar and style at first. Just get your ideas down. After that, you can go back and refine your writing, adding more details to the descriptions, making the dialogue more natural, and ensuring the story flows well. Also, it's a good idea to get feedback from other fans of the Blade of Marmora or the Voltron series in general.
Keith will likely be defiant. He has a strong sense of justice and will not be easily broken by Zarkon. He might try to fight back immediately if he has the chance.
One of the main characters could be Shiro. Shiro has always been like a big brother to Keith. So when Keith turns into a girl, Shiro would be there to help him adjust. He'd make sure Keith is safe and comfortable in his new form. Also, Hunk could be a main character. Hunk would probably be the one to offer emotional support and cook some comfort food for Keith during this tough time of adjustment.
I'm not sure if there is a specific 'pregnant Keith fanfic' available. It depends on the fandom and the amount of fan - created content out there. You could try searching on popular fanfic websites like Archive of Our Own or FanFiction.net.
I think Keith's closest friends within the blades are most affected. If he's younger, they might become more overprotective. If he's older, they could start relying on him more for advice. For instance, if there's a character named Lance who was previously on equal footing with Keith, now he might see Keith in a different light depending on his age.
