First off, good luck!!! Have you looked at the RBA thread on the DE board at Feetile thoughts under the infertility forum? Quite a few ladies whose envies did not meet the guarantee when transfer occurred wound up pregnant. As such, don't give up hope. I would have a lot of hope. These are two embies of a young donor. I'm surprised that your RE said that too you. Maybe he/she just wanted you to know that worse case scenario, they would honor their guarantee. Do you know yet if you have any frosties? I am cycling there now myself and it makes me feel good when I hear that they actually honor their guarantee. I think you should check out the RBA thread. You will see quite a few successes in your position.
