Week 10 but scan shows the foetus not growing at week 7, with heartbeat

This morning I went to NUH for my 2nd scan. My week 10 scan. Doc did both tummy and vaginal scan and told me that my foetus is not growing, measurement still about the same as week 7. With heartbeat. I had a week 7 scan at A&E due to bleeding and cramps. Was given proluton jab and bleeding stopped till now. Everything's good till today, no cramps, no bleeding/spotting. My first week 6 scan and week 7 scan, can still see the baby has grown. Doc said to schedule a more detailed scan at fetal care centre as the machine is more high tech.. which is 2 weeks from now. Only after the scan, then she will be able to provide more information.. Anyone had the same experience before and be able to advice if the baby is gonna make it? I'm devastated. And the waiting time is way too long. Have booked a private scan next Monday.
