Donbean - try posting on miscarriage/bereavement and you will find that there are lots of people out there, unfortunately, with experience of m/c and no doubt some with experience of blighted ovum. I had a m/c on Friday and think it might have been this as there didn't seem to be anything at all in the little sac that I passed. If you do post on miscarriage/bereavement, I'd suggest you try and be specific about the information you want...
