A plotline might also involve Harry's relationships changing. As a girl, his/her romantic relationships could take a different turn. The pregnancy could add an extra layer of complexity. For example, if there was a previous romantic interest in a female character, that dynamic could shift completely. Also, there could be a sub - plot about how the wizarding society views a pregnant, transformed Harry, and the challenges he/she faces in a world that has certain expectations and norms.
I'm not sure specifically which 'pregnant Harry turned girl' fanfictions are out there. You could try searching on fanfiction - specific websites like Archive of Our Own. They have a vast collection of fan - created works and you might be able to find something related to this rather unique concept.
Another storyline might involve Harry having to hide his condition from Voldemort and his Death Eaters, as being in a vulnerable pregnant state makes him an even bigger target. He could also form unexpected alliances with female characters who help him through this difficult time.
As a girl, Harry's character would likely become more attuned to the subtleties of communication. In the original story, Harry was straightforward and to - the - point. But as a girl, she might use more nuanced language and body language to convey her thoughts and feelings. Her sense of style could also become an important part of her character. Maybe she starts wearing different robes or accessories that reflect her new identity. This could also influence how she is perceived by others and how she perceives herself. She might also be more likely to rely on her female friends for support rather than always trying to handle things on her own as she did before.
It could be Ginny Weasley. Since they have a relationship in the original series, it's not too far - fetched to imagine a scenario where she gets pregnant. Maybe they got carried away during a time of peace in the wizarding world.
One interesting plot could be Harry having to deal with the different social expectations placed on girls. For example, in the wizarding world, there might be different rules or attitudes towards female students in Hogwarts. He might struggle with how to act in a way that is considered 'appropriate' for a girl while still maintaining his own identity.
Another plot could involve Harry's friends' reactions. Some might be very accepting and helpful, while others could be confused or even act differently towards 'her'. This could lead to some interesting character development and story arcs for both Harry and his friends.

In such a fanfiction, Harry might face a whole new set of challenges. For example, he would have to deal with the different ways people treat him as a girl. His friends might be initially shocked but then gradually accept this new version of him. He could also use this new form to his advantage in some situations, like getting closer to certain characters who were previously more guarded around him.
One way the story could progress is that Harry, now as a girl, could infiltrate female - only areas in the wizarding world. This could lead to uncovering secrets that were previously hidden from male characters. He might also have to deal with unwanted attention from some male characters, which would add a new layer of conflict to the story.
