Another option is Wattpad. There are many writers on Wattpad who create fanfiction. You can search for 'Katherine pregnant' and explore the results. Sometimes, you might even find some lesser - known but really interesting stories written by emerging writers on this platform.
One popular 'Katherine pregnant fanfiction' might be one where the story focuses on how her friends and family react to the news. They could be initially shocked but then rally around her to support through the pregnancy journey.
The main characters are clearly Elijah and Katherine. They are the central focus of this fanfiction, especially since the title mentions them directly and the pregnancy is related to them.
Well, it could be about how they deal with the unexpected pregnancy. Maybe they struggle to accept it at first, then gradually come to terms and start preparing for the baby.
One common plotline is the reaction of other characters. For example, how Klaus's family members or Katherine's friends react to the news. Some might be happy, while others could be shocked or even opposed to it.
Their relationship would likely become more protective. Elijah would be extremely protective of Katherine and the unborn child. He might become more possessive in a way, not wanting to let any harm come their way.
Caroline would likely be a mix of excited and cautious. She's a bit of a romantic at heart, so she might see the potential for a new family dynamic. However, she also knows Katherine's past and would be on guard to make sure Katherine doesn't manipulate Damon during the pregnancy. She would probably try to befriend Katherine to keep an eye on things.
Perhaps the pregnancy is a sign of a new vampire - related phenomenon. In the fanfiction world, it could be that a new type of vampire is emerging, and Damon and Katherine are the first to experience this pregnancy. This could lead to them being hunted by other vampires who either fear this new development or want to study it for their own gain.
I'm not sure if there is specifically a fanfic with that exact plot about Katherine Summers. There are so many fanfics out there that it's hard to say for certain without doing a very in - depth search in relevant fanfic platforms.
One idea could be that they face challenges from the supernatural community due to their unborn child's potential power. The other vampires or witches might see the baby as a threat or a valuable asset. Another plot could be them preparing for the arrival in a world full of danger, like building a safe haven and gathering allies.
