Loosing our baby

Rebecca
I had a scan 10 days ago to be told I was 6 weeks when I thought I was further. I went back today for another scan to be told i only measured 6 weeks 2 days. Looks like baby isnt growing right. A heartbeat was seen but was very low. I called the early pregnancy unit but they won't see me till Friday. Feel numb and like I am just waiting to lose the baby 😔xx
