Another could be Annabeth dealing with her own insecurities about motherhood while still trying to be her strong, intelligent self.
A plot idea could be that Annabeth discovers some sort of prophecy related to her unborn child. This would add an element of mystery and adventure. She would then have to embark on a quest, even in her pregnant state, to ensure the safety and future of her child, all while relying on her friends and her own wits more than ever.
One idea could be exploring how Percy and Annabeth deal with the impending arrival of their baby in the context of their demigod lives. Maybe they have to protect their unborn child from some mythological threats.

Another could be the challenges she faces during the pregnancy, like her still wanting to be involved in heroic adventures but having to be more cautious.
The fanfic could be about Percy and Annabeth's kids participating in a friendly competition within the camp. It's a series of challenges that test their physical strength, strategic thinking, and teamwork. Through this competition, they learn more about their own abilities and the importance of working together, while also having some fun rivalries with other demigod kids.
A great plot idea is that the child has a special connection to the sea, like Percy, but also has Annabeth's wisdom. So they use this combination to solve a mystery that has been plaguing Camp Half - Blood for years. For example, the mystery of why some demigods' powers are fading. Another could be that the child gets sent back in time and has to interact with their parents when they were younger. This could create some really interesting situations and challenges for the child.
A possible plot could involve a magical tournament where Percy and Annabeth are on opposing teams. Their rivalry gets in the way at first, but as the tournament progresses and they see the real threats emerging, they start to cooperate in a more covert way to ensure the safety of everyone involved.
One idea could be focusing on the emotional journey of the character. She might feel a mix of overwhelming joy and intense fear.

Or perhaps the story could revolve around how the family and friends react to this big news.
A possible plot for a 'Ranma 1/2' pregnant fanfic is that it's a result of some magical mishap. This could lead to a search for a way to reverse it, but during that time, Ranma and Akane (or whoever is involved) start to bond in new ways. They could learn more about each other's fears and hopes for the future. Or perhaps it's a plot where an enemy discovers the pregnancy and tries to use it against them, forcing them to come up with creative ways to protect themselves and the unborn child.
Well, they could face a situation where they have to go into hiding during the pregnancy because of the dangerous nature of the clone world. They might find a secluded place where Cosima can have a peaceful pregnancy, but of course, trouble still finds them. Maybe some old enemies track them down, and they have to use their wits and the help of a few trusted friends from the Clone Club to stay safe.
One idea could be exploring how Clary's relationships with her friends and family change. For example, her friends might rally around her to support her during the pregnancy.

Maybe she has to learn new magical ways to take care of herself and the baby since she's in a unique situation.
One idea could be exploring how Hawkgirl copes with her pregnancy while still having to protect the city. Maybe she has to balance her new physical limitations with her superhero duties.
