But we are so sad and disappointed over the loss of the one. I know and knew the stats were not good, given that this is an invetro pregnancy and my DIL's age are factors that gave odds of 70% demise early in the first trimester. But knowing that doesn't take away the hope and desire and excitement. I'm not sure if this loss comes under the heading of Vanishing Twin Syndrome, but it sure sounds like it. You can read about it on that link.
Thank you for letting me share this with you.
