Sounds JUST like my BFF last year... they told her to come back in a week and made it seem like all was good. We all tried to stay upbeat because she had been trying for 2 years at that point.
But in the end the baby was never there. They called it a blighted ovum... She had to have a DNC :(
BUT as of today she is 12 weeks prego and everthing is GREAT! So don't give up hope even if this doesn't turn out well! Just keep trying!!!
