A lot of Portal Chell pregnant fanfictions play with the idea of the father. Some might have it be an OC (Original Character) that was also a test subject, and they met during their trials. The story could then revolve around how they reunite and deal with the news of the pregnancy, all while still being in the strange and dangerous world of Aperture Science.
The back story of Chell in Portal involves her being a test subject in the Aperture Science facility. She wakes up in a strange, sterile environment and is forced to participate in various portal - related tests. The facility, run by the malevolent GLaDOS, is full of dangerous and mind - boggling test chambers. Chell's main goal is to survive and escape this crazy place.
Family is also a common theme. Since Chell has been mostly alone in the Portal games, the pregnancy forces her to think about creating a family. This can lead to her reflecting on her own past and the lack of a family she had before. Some fanfictions explore how she might try to create a loving and nurturing environment for her child, even in the midst of the insanity of Aperture Science.
The key elements include Chell as the test subject, Aperture Science as the setting, and GLaDOS as the main obstacle. Also, the portal technology which is central to all the tests she has to go through.

However, as the story progresses, Wheatley's actions take a more sinister turn when he gets power - which creates a rift between them. Overall, their relationship is a key aspect that drives much of the fanfic's drama and plot twists.
