missed miscarriage

I had my first scan at my ob yesterday. They found an empty sac. I would have been 11 weeks. The sac measures 11 weeks. I'm still experiencing all pregnancy symptoms - I still have morning sickness. I go to the hospital this morning for more scans and to talk about the next steps. I am terrified and heart broken. I feel so let down by my body. The morning sickness has been so hard and right from three weeks, I needed a baby to make it all worth while.
