BW, once again can I say how sorry I am for the loss of your darling little one.

I have had a blighted ovuum and was told that it was when the egg had failed to grow successfully although there would still be a yolk sac visable. They said that there would never have been a heartbeat to see. A missed miscarriage is where the baby has died but the actual miscarriage process hasn't started. Sometimes the loss of the baby is only discovered when the woman goes for an U/S.

Hugs and good wishes,
Debbie
