Well, in some fanfictions, Alice's visions play a crucial role. She might see different possible futures for their unborn child, which creates a lot of tension and mystery. Also, Jasper's past military experience can come into play when it comes to protecting his family. He might be extra vigilant and plan for all kinds of threats.
One idea could be a story where Alice and Jasper travel back in time to their human days and have to deal with their past selves. Another could be a scenario where they get separated during a battle with a new group of vampires and have to find their way back to each other. Maybe a story where they discover a new power together that only they can use as a couple.
One possible plot twist could be that the pregnancy is not a normal one. Maybe there are some special powers or abilities that the baby inherits which causes all kinds of chaos and challenges. For example, the baby could have the power to manipulate time like Alice, but it's out of control in the womb and affects the flow of time around them.
One common theme could be the anticipation and excitement of new life. Since Alice and Jasper are characters, their reactions to the pregnancy would be explored, like Jasper's protectiveness perhaps.

A plot could involve them moving to a new place during the pregnancy. They might discover a new community that either accepts them wholeheartedly or makes their situation more difficult.
