Bella55 Welcome and double congrats for your little surprises in your tummy. It sounds like you are telling my story the same thing happened to me through IVF. I transfered 1 blast and it split, what IVF did you go to. Did they tell you what sort of identical twin you have? I also did the same thing when I found out I jumped straight on to the net and found horror stories, I stopped doing that and am now reading a book called (Twins by Katrina Bowan and Louise Ryan) its a great read and helped me with some of the answers I had. It starts from conception to preschool.
I am now 11 weeks and 2 days getting closer to that 12 week mark.

Kazzabird I hope that at my next scan they will see a faint line between them Im not to worried about the twin to twin transfusion as I know that they can do something about that but if they get tangeled there is nothing they can do depending on how far long you are to do a emergancy C secton. Thanks for tell us about how many scans you get I was about to ask that question.
