No offense, but Catherine of Aragon being pregnant is pretty unlikely IMHO, not necessarily impossible, since legally the theory goes that there is such a thing as a fertile octagenarian. But the woman hasn't borne a child in +-20 years, and suddenly she's got a bun in the oven. At her age (around 51)? Something tells me that there's gonna be a lot of likening of Catherine to St. Elizabeth (mother of St. John the Baptist).
Worse than that', he has Anne Boleyn actually committing incest with George before her marriage to Henry (in which case it would lead only to George's execution, but in any case there isn't a historian I know of that believes it really happened IRL); Fitzroy marrying before it was legally possible for him to do so (fourteen was the minimum marriage age for boys at this point); Clement throwing away his niece on a bastard he hardly knew for no advantage at all (I mean, come on); Katherine of Aragon giving birth 15 years after she entered menopause; and strangest all, Henry VIII "never becoming Protestant", as if this was a huge POD.
Henry VIII was never Protestant for a moment of his life. Not for a moment.
