What if Katherine of Aragon was with child when Arthur died,
So, when I read this, my first thought was 'what changed so that Katherine becomes pregnant?"
Now I know it anecdotal, but there are a lot of stories of people who've struggled with fertility adopting and then getting pregnant. The theory I heard was that something about being around a baby helps the body conceive.
So, the POD I came up with starts before Katherine falls pregnant; Prince Edmund Tudor doesn't die in 1500, and it's his presence that triggers Katherine's fertility.
Then when, after Arthur's death, Katherine gives birth to Elizabeth Tudor, the Tudors have their slightly complicated inheritance issue. Henry VII solves it by betrothing Henry and Elizabeth. The Pope grants dispensation. The slightly more protected inheritance, Elizabeth and Edmund in addition to Henry, ensures Elizabeth of York has a smoother pregnancy and she safely delivers Katherine Tudor.
