Bbhope.... ummm... anon donor is unknown.... sorry, or do you mean something else? I would have been happy asking one of DH's distant male cousins, but he was dead set against it. With anon, the baby would be totally ours - no-one looking at it, thinking things.
Jenni... that's the problem.... I've been tested for everything... Believe me, everything!! There is no explanation, my insides are all perfect, my periods and cycles all perfect, a few immune issues, but that's it. No FS has any ideas really what can be done.
