Yes, they are quite popular among certain readers. These novels often explore complex relationships and emotions. The idea of a mistress being pregnant adds a layer of drama and intrigue to the romantic plot.
Well, in these novels, a major theme is the conflict between passion and responsibility. The hero may feel passion for the mistress but also has a sense of responsibility towards his existing relationship or family. Another theme is the transformation of the characters. The mistress, upon becoming pregnant, may transform from a carefree individual to someone more mature and concerned about the future. Also, the theme of redemption often plays a part, where characters try to make up for their past mistakes in the context of this complex relationship.
The implications are numerous. In a fanfiction where Hermione is Lucius' mistress and pregnant, it would be a major deviation from the original narrative. Hermione's relationship with her Hogwarts friends would be strained, if not completely broken. Harry and Ron might feel betrayed. From a magical society point of view, it could cause a scandal. The Malfoy family might also have mixed reactions. Lucius' wife Narcissa might be furious, and Draco would have to deal with this new family situation. And Hermione herself would have to struggle with her own identity and the choices she's made, as well as the consequences of her pregnancy in a world full of magic and danger.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide range of very creative and sometimes controversial ideas, but this particular scenario seems rather unorthodox and not a common theme in mainstream fanfiction.
They often involve secrecy and forbidden love. In novels like 'Lady Chatterley's Lover', the relationship between the mistress and her lover has to be hidden from society. This secrecy adds to the tension and allure of the story. Another aspect is the exploration of the mistress's inner world, her desires, and her struggle between love and morality.

In other cases, the mistress relationship may end in heartbreak. The mistress might be left alone as the man she was involved with returns to his original life. These endings can be quite tragic and are often used to show the consequences of engaging in such complex and often frowned - upon relationships.
One common theme is forbidden love. Since the relationship of a mistress is often outside the bounds of traditional marriage in historical settings, the lovers face many obstacles. Another theme is power dynamics. Often, the man may be in a position of power, like a noble or a wealthy merchant, and the mistress may be in a more vulnerable position. Social status is also a theme. The mistress usually has a different social standing compared to the man, which adds to the complexity of the relationship.
I'd recommend 'Secret Desires'. In this novel, the heroine's role as a mistress leads to a web of emotions and hidden secrets. It explores the depth of her feelings and the consequences of her choices.
