I really like 'Lip Gallagher and the Reader: A New Beginning'. In this fanfic, the author does an amazing job of creating a believable scenario where the reader character enters Lip's chaotic world. It shows how they both grow and change because of each other, and the dialogue is so on - point with Lip's personality.
Archive of Our Own (AO3) is a great place to start. It has a large collection of 'lip gallagher x reader fanfic'. You can easily search for it using the relevant tags and filters. Fanfiction.net is also another option, although the tagging system might not be as refined as AO3.
There are fanfics where the OC helps Lip deal with his family issues. In these stories, the OC might have a stable family background themselves and offer Lip a different perspective on family dynamics, which is quite interesting.
Family reactions are probably also a big theme. The Gallaghers are a close - knit, if chaotic, family. So the story could explore how his siblings, father, and the rest of the family react to the news of Lip having a baby on the way. Some might be supportive, while others might be more skeptical or worried about how he'll handle it.
One idea could be that Lip discovers the pregnancy of his partner and has to quickly adapt to the idea of becoming a father while still dealing with his own personal and family issues. Maybe he struggles with his studies or job because of the added responsibility.
Fiona could be an interesting choice. Since she has always been a mother figure in the family, her reaction to Lip's situation would be complex. She could be both supportive and a bit overbearing as she tries to guide Lip through the pregnancy journey.
Set an interesting plot. It could be something like Lip and the OC getting involved in a local community project. This gives them a chance to interact and develop their relationship. Also, add some drama or conflict, like differences in opinions on how to run the project.
I'm not sure about specific Lip Gallagher pregnant fanfic stories. You could try searching on fanfiction platforms like Archive of Our Own. They usually have a wide range of fan - created stories, and you can use the search function to look for ones related to Lip Gallagher and pregnancy.
