I think what has changed my plans with all of this is the identical twins situation, I just feel I need to know as soon as possible now but maybe I am being hasty, I am going to try to think about it some more over the next week and I pray that when I meet the peri I will feel confident with whatever I decide. I was just wondering if there were certain risk factors that may predispose someone to doing worse with the procedures. I am sure the peri can tell me if so. Thanks and good luck with your baby.
