I experienced something very similar.
I found out at 7 weeks pregnant that my baby never developed. The gestational sac and placenta were healthy and normal sized. My doctor did a repeat ultrasound at 8 weeks and it showed the gestational sac and placenta had grown, but there was still no baby. He called it an "anembryonic pregnancy" (or blighted ovum).
During that week, I read a lot of accounts where the baby just couldn't be seen yet. Don't lose hope!
So sorry Honey. I had been experienced the same thing. I know how it feels to be frustrated, scarred and wonder if you will ever be a mom. You have to be strong and have a hope you wil have good luck next time and everything will be fine. Be strong there!!!
