MrsErinR and Felicity Fox - congratulations on moving from PUPO to BFP.
Canuck and Faith - that's very sad.. I think we've all been there and know how devastating it is, the self doubt and self loathing, and the questions rattling through your head. Hopefully you have a Plan B (and backup Plan C). Love and hugs to you both, and all our BFNs of late.
ECM - ask CFC which one. They will be able to give you straight answer. They might tell you to go with one over the other because of egg quality or numbers etc. I asked about three girls and got an answer straight away. The choice was obvious for us once CFC told us their cycle histories.
