One possible storyline could be how Rachel's pregnancy affects her dreams of stardom. Maybe she has to put her Broadway aspirations on hold and deal with the reactions of her friends and family in the Glee club. Another could be about the father of the baby, if it's Finn, how they navigate their relationship while also preparing for a new life. Or it could focus on how the pregnancy changes her role within the Glee club, like taking on more of a mentoring role to the younger members as she experiences this major life event.
Finn is very likely to be involved. If he's the father, he would have a huge role in the story. He'd need to deal with his own feelings about becoming a father so young and how it affects his football and Glee club activities. Quinn could also be involved. She might offer Rachel advice based on her own experience with pregnancy, even though their situations were different. And of course, Mr. Schuester would be there. He'd be like a mentor to Rachel, guiding her through the tough times and making sure she still has a place in the Glee club.

One popular storyline could be how Rachel and Finn deal with the reactions of their friends and family. Their friends in Glee club might be initially shocked but then come around to support them.
