AFM... that's another one... unfortunately the HPT says BFN. Today is 10dp6dt. AF is due today, just tiniest colour so far. Will wait until she's here properly before phoning clinic and make new appointments. Phoned and made a new appointment with Dr M (shaking head, really wondering why). Keep hoping that my sister's donor eggs couple with donor sperm will do the trick, but that's two used, two to go. Looking like it's nothing to do with the eggs or sperm and all to do with me. Strangely though there's no explanation - uterus perfect, lining perfect etc. It's hard just to blame it on percentages - would like a more definite reason than that, but I know there isn't going to be one.
