In this fanfiction scenario, Kara being pregnant and Mon - El leaving could lead to a complex story. Maybe Mon - El leaves because he fears for Kara's safety due to her pregnancy and his past or some external threats. Kara is left heartbroken and pregnant. She may initially be in denial about Mon - El's departure, but then has to face reality. As she goes through the pregnancy, she could meet new people who help her, like other superheroes or just kind - hearted civilians. And throughout the story, there could be a lingering hope that Mon - El will return, but also a growing sense of self - reliance in Kara as she prepares to be a mother alone.
Even though Mon - El leaves, their relationship can still develop. Kara could keep a journal for the baby, writing about her feelings for Mon - El. When Mon - El returns (if he does), he could read it and realize how much Kara truly loved him. Also, Kara might have dreams or visions of Mon - El during her pregnancy, which could show that their connection is still strong on an emotional level.
