In fanfiction, anything can happen. However, without specific details of the particular fanfic, it's hard to say for sure if Serena is pregnant. Some fanfictions might explore this plotline for the sake of drama or character development. It could add an interesting twist to the relationship between Ash, Serena and Lemon, but it also depends on the overall theme and direction the author wants to take the story.
One idea could be a story where Ash, Serena and May team up for a special Pokémon tournament. They each bring their unique skills and Pokémon to the competition. Along the way, they face challenges that test their friendship and teamwork. For example, they might have to deal with a devious trainer who tries to sabotage them.
In some fanfictions, Ash might develop a special bond with both Serena and May. For example, they could be exploring a new region together and encounter a rare Pokemon. Serena could use her knowledge of Pokemon behavior to track it, May could come up with a battle plan, and Ash would be the one to catch it. This kind of adventure would strengthen their friendship and show how well they work together.

Misty had a feisty relationship with Ash. They were like two kids always bickering but having a deep bond. May's relationship was more about shared goals in the Contest world and learning from each other. Dawn was similar to May in the Contest aspect, but her friendship with Ash seemed more innocent and supportive. Serena, she had a relationship with Ash that had a touch of romance. She was inspired by him and as they traveled together, her feelings grew. Each relationship is unique and offers different possibilities for fanfiction writers to explore.
