Thanks girls - I haven't heard from my friend Mick about his wife yet. I think I will wait until tomorrow to ask.
I was talking to my mum and she said that it could be that the dead foetus is infecting the uterus which is causing her to be sick.
Apparantly my Aunty had this same prob and she had to terminate the pregnancy because the healthy bub was suffering.

Oh I am hoping that is not the case [-o<
