IVF gone wrong: One woman carries another couple's baby to term

Carolyn and Sean Savage spent years trying to have another child and, after four miscarriages, Carolyn finally got pregnant after in vitro fertilization.

But the Savages were devastated when they learned the embryo Carolyn was implanted with wasn't theirs. Still, the Savages made the decision to carry the baby to term for the other couple. Carolyn and Sean document their story in their new book 'Inconceivable: A Medical Mistake, the Baby We Couldn't Keep, and Our Choice to Deliver the Ultimate Gift" and tell Kiran Chetry their story this morning.
