Lily may focus on taking care of herself during the pregnancy. She'd ensure she has proper medical care, eats well, and gets enough rest. This would be a way for her to take control of the situation in a positive way. Also, she might consider reaching out to her family for help, if they are on good terms. They could provide practical assistance like helping her find a suitable place to live if needed.
One challenge could be financial. They might need to figure out how to afford things like baby clothes, a crib, and medical expenses. Another might be emotional stress. Lily could have mood swings during pregnancy, and James might struggle to keep up with her changing emotions.
There are fanfictions where the pregnancy is a central theme in a story that looks at the family's past. For example, it could be told from the perspective of a family heirloom. The heirloom has been passed down through generations and during Lily and James' pregnancy, it starts to show strange signs. It could be a magical object that is somehow linked to the fate of their unborn child, and as Lily's pregnancy progresses, the mystery of the heirloom unfolds.
Some 'james lily pregnant fanfiction' stories could focus on the magical aspects of the pregnancy.
