One common theme is the relationship between Magnus and those around him. His partner, whether it's Alec or someone else in some fan interpretations, might be shown as being very protective. Another theme could be the magical implications. Since Magnus is a powerful warlock, there could be speculations about how his magic is affected during pregnancy. And of course, there's the theme of anticipation and preparation for the new life, which might include things like creating a safe space in his magical lair for the baby.
One common theme is the exploration of family. Since Magnus is pregnant, it often delves into how he and his partner (usually Alec) will form a new family unit and what that means for them. Another theme is the fear and excitement that comes with pregnancy. Magnus, being a warlock, has his own set of concerns about bringing a new life into the world, and this is often explored.
One common theme is his magic and power. Writers often explore how Magnus uses his magic in different situations. Another theme is his relationships, like his romantic relationships or friendships. His backstory also features a lot, especially his experiences growing up as a warlock.
One common theme is vulnerability. Since Magnus is often seen as a powerful warlock, these fics explore what happens when that power is stripped away, even if just temporarily, due to injury or emotional pain.
Emotional hurt is also quite prevalent. For example, his relationships with the Shadowhunters might cause him pain. Maybe a betrayal by someone he trusted, like Alec or one of the other characters, which can lead to a lot of angst in the fanfiction.
Love and acceptance are very common. Given that they are from different worlds (Shadowhunter and warlock), their relationship often involves them learning to accept each other's differences. Another theme is family. Alec has his Shadowhunter family and Magnus has his own kind of 'found family' among the Downworlders. Fanfictions often explore how their relationship affects and is affected by their respective families.
Love is a major theme. The love he has for the unborn child, the love from his partner (if there is one in the fic), and the love from his friends and family. Also, the theme of fear is prevalent. Magnus is likely to be afraid of the unknowns of pregnancy, such as the health of the baby and his own well - being during the process.

One plot idea could be Magnus trying to balance his powerful magic with the changes in his body during pregnancy. He might be worried about how his magic could affect the unborn child. Another could be the reactions of his friends and family. For example, Alec might be over - protective and trying to keep Magnus safe from all the possible threats in the Shadowhunter world. And Magnus could also be facing challenges from the Downworlders who might see his pregnancy as a sign of weakness or a change in the power dynamics.
