Isolation is also a theme. Vampires are often solitary creatures, and venom - infused beings might be feared or shunned. So, the stories might explore how these characters deal with their isolation and whether they can find a place to belong.
The idea of Venom being an outcast is also common. Fanfictions may show how he tries to find his place in the world, whether it's among humans or in a world of his own kind. It adds depth to the character and makes for an engaging read.
One common theme could be the exploration of new family dynamics. Since it involves a 'pregnant' situation in the context of Venom, it might look at how the characters adapt to this new state.
One common theme is the struggle for coexistence. Since Venom is a symbiote and Eddie is a human, they have to figure out how to live together in harmony. Another theme is redemption. Sometimes in fanfiction, Eddie or Venom has a past they need to make up for. And of course, the theme of friendship and loyalty is always there as they depend on each other.

And the theme of the symbiotic relationship itself is also very common, exploring how Eddie and Venom depend on each other.
One common theme is the idea of protection. Spiderman will always strive to protect the pregnant character, whether it's someone he loves or an unexpected result of some strange event. Another theme could be the exploration of the unknown. The pregnancy is something that's not normal in their world, so they have to figure out what it means and how to deal with it.
