Brittany's parents should be in the story. Their reactions to her pregnancy could range from disappointment to full - on support, and this would add a lot of depth to the story. Also, Tina. She could be a great friend to Brittany, sharing her own fears and hopes for the future. And don't forget Finn. He could be the one who encourages Brittany to keep going with the glee club, saying that it's important for her and the baby to have that creative outlet.
Finn Hudson could be an interesting character to include. He might be a bit clueless at first but then grow to be very protective of Emma and the baby. Santana could add some drama and spice to the story. Her sharp tongue could either be used to support Emma or cause some trouble, depending on the plot. Puck could also be in the story, perhaps he offers a different perspective on fatherhood since he has his own experiences related to it in the show.
Quinn would be a great character to include. She has her own experiences with pregnancy in the show, so she could offer Rachel advice and support. Also, Kurt could be there for Finn, as they are good friends. Kurt might give Finn some practical tips on how to be a good father - to - be and how to handle the situation in a more stylish way.
There is a fanfiction where Artie has a crush on Brittany and he tries to express his feelings in a very unique way. He writes a song for her, but there are misunderstandings along the way.

Chat Noir is an obvious choice. His relationship with Ladybug is so central to the original story, and with her pregnant, his reactions and support would be a great addition. Marinette's best friend Alya could also be included. She could be the one Ladybug confides in, and Alya could use her journalistic skills to help keep Ladybug's pregnancy a secret if needed. And Master Fu could be in the story. He could offer his wisdom and guidance, especially when it comes to any potential threats to Ladybug or the unborn child.
In some fanfictions, the plot could revolve around Brittany and her partner. For example, if her partner is Santana, they could have different reactions to the pregnancy.

The two main characters are Alvin and Brittany. Alvin is known for his impulsive nature and his close bond with his brothers. Brittany is part of her own group and has her own set of friends. In this 'pregnant fanfiction', they are the focus. We can expect to see how their individual traits play out as they become parents - to - be. For example, Alvin's spontaneity might need to be toned down a bit, and Brittany's poise might help them face the various situations that come with pregnancy.
It could be Artie. Maybe they had a moment that led to this unexpected pregnancy.
Definitely their friends from the show. Bonnie could be a great addition as she might be able to use her magic to protect Caroline during the pregnancy. Klaus could also be an interesting character to include. He has a complex relationship with both Tyler and Caroline, and his presence could add some drama and conflict, like he might try to use the baby for his own purposes.
Definitely her sisters, Phoebe and Paige. They are her closest family and would be there for her throughout the pregnancy. Leo, as her husband, is also crucial. He can provide support and love. Then there could be some of the recurring good witches or magical beings who could offer their help or advice. For example, Grams could appear in Piper's dreams to give her some grandmotherly wisdom about motherhood.
