Well, often in such fanfictions, the theme of growth and change is prominent. Santana's pregnancy could be a catalyst for her personal growth. It might also involve themes of support systems. Who is there to support her during this time? Is it her friends, her family, or is she more on her own? And of course, there could be themes related to the anticipation of motherhood, like her preparing for the baby, dealing with pregnancy symptoms, and all the emotions that come with expecting a child.
Another theme might be her own internal struggle. If Santana is a strong - willed character, she may have to deal with the conflict between her own goals and the new situation of being pregnant. She could be worried about how it will affect her future, her career (if applicable in the story's context), and her identity. Also, the relationship with the baby's father would be a big theme. Whether they are in a loving relationship or it's a more complicated situation, it would add a lot of drama to the fanfiction.
