We had 2x 3 day embies put back we weren't afraid of twinies or more either and that TF resulted in our DD. So just because you put 2 back doesn't always mean that twinies will take.

We chose to put 2 back because of the success rate. It's not much more than TF'ing 1 but a % is still a % and the more % we have the better I thought.

We will be cycling in Dec (if AF arrives before the 5th Dec) and we are putting 2 frosties back again.
