Has anyone gone to obgyn and have two U/S and the dr couldn't see the Baby or heartbeat only the Sac??   I have never heard of this. What should I do?  I was told to do a D&C but I'm not sure if that's what I need to do.  What if there is a Baby!!  Please help! All the opinions and advice will really be appreciated!!!
