Missed miscarriage

Tabitha
I was told a week ago that my baby had stopped growing 6 weeks ago. It's now 7. I have another scan next Friday which will then be 8 weeks. I'm still waiting for the loss. I have been very emotional up till now, but today I don't feel sick or pregnant at all. Is this normal? I keep thinking that I will go for this scan next week and they will say I'm not pregnant, or it's gone!! I saw it on the monitor so I know it was. Can u loose it and not know?? I'm so confused right now
