I don't think so. Biologically, I don't think it's possible - she doesn't share the same number of chromosomes with humans, vampiros or werewolves, so there is no way she could conceive. Besides, I was always under the impression that once she came of age and stopped growing and the most noticeable aspect of human has gone, she would seem mais vampire and female vampires' bodies can't physically change to accommodate a baby.
She shouldn't even be alive. Smeyer made it pretty clear that vampiros don't breath, and don't have a coração beat In turn they have no body fluids. So technically Edward couldn't have reproduced with Bella. Making her was just a plot device ( Very poorly made ). No, each creature is designed so that they can only reproduce with the same type of creature. If she had a kid with another half human ( Again shouldn't even be possible, but in Smeyers world science dosent matter.) maybe.
well she is half human and half vampire so it could be possible but she might be in pain because vampiros cant give birth to a child they can only bite people to make them die or change to a vampire but still it could be possible
It ought to be possible for a short window of time before she hits complete maturity and freezes at her current age. The fact that she was imprinted upon does strongly suggest she'd be able to have at least one child. And I'm ignoring the chromosome numbers because it was only mentioned once, and I don't think Stephanie Meyers realises that it makes the entire story impossible.
