@Leisylou your post brought tears to my eyes. Of course you can feel 100% joy and love and commitment to a baby and still grieve the loss of your own biological child. I hope you got though to your partner, I guess sometimes we just have to spell it out to them.
Yes I think DE might be 60% but that might be with a double transfer? Someone might know.
I was quite slow to come to the party with babies too. It was definitely a very slow dawning for me
Sorry about your BFN I have every confidence that Wazza can come up with a more gentle protocol for you. Its a bit pointless if its so full on you can't go through with it!
