What an inspirational story, my eyes are welling up with so many emotions:
'happiness' - that your embies are on board
'sadness' - of your dear husbands prognosis, that is so hard I cannot imagine
'admiration' and 'gratitude' - that you were one of the first donors some years ago
'hope' - that this will turn into a BFP cycle for you and dh. You both absolutely deserve it.
I am wishing for the very best outcome for you both and looking forward to hearing your updates.
