It could be really interesting to read a fanfiction like that. The alpha and omega universe has its own set of rules and dynamics. A story about Claudette being pregnant might explore how she copes with the changes, how her relationships with other characters are affected, and what new adventures or challenges she might face during this time. There could be themes of love, family, and the struggle to adapt to a new situation, all within the unique context of the alpha and omega world.
I'm not sure if there are many fanfictions specifically on this topic. You could try searching on popular fanfiction websites like Archive of Our Own. Maybe start by looking for alpha and omega fanfiction and then filter for stories where Claudette is pregnant.
