I'm sorry, but you have to die at the end.
It's nothing personal, it's just part of the plan, see? 'Cuz if I don't kill you, then Emilio and Callista can't become full-fledged vampires by drinking your blood. And they're such nice kids. They deserve more than a cold eternity of being un-dead.
And besides, you're a bitch.
(And it's your own damn fault you got pregnant - you shouldn't have been where you were when the moon came out from behind that cloud and you know it). Sorry. That's just the way it is.
Best of luck to you in your next life,
