Is Prince William's fiance already preggers?

I am thinking that the whole thing has been engineered by the Queen who wanted to make sure that an heir would be available to block any attempt by the illegitimate Harry Son of Hewitt from sitting on the throne. This is Diana's last bombshell. She produced a basterd son who might take the throne from the Windsors. They cannot allow this so mus tmake sure that William is either not infertile or gay (I have a sneaking suspicion he might swing either way). And also they would be embared to expose Harry should he be up for the throne. So it seems Willies wife is preggers, no?
