Keep in mind as well that just because you transfer 2 it's not a guarentee of a twin pregnancy. We had 2 put back and had a singleton pregnancy and we also had 2put back in our FET and had 1 stick but ended in a blighted ovum.

We decided on putting 2 back because of the % of success. It increased our chance by 1% but that was still 1% more than we had. Yes we understood we "could" end up with multiples but that was a chance we were willing to take.
Hey Porsche!
That's so true & your the not the first by the look of it to result in a singleton after 2 ...
I understand the need to be mentally prepared for the possibilities both neg & pos :-)
