emergency growth scan

Well yesterday I did my 3rd trip to hospital in a week.
This time it wasn't for cramping but for reduced fetal movements.
I hadn't felt my baby move as much as usual. Some will say that is normal and to be expected as there is less room for baby to move., but having looked on the NHS website before phoning the hospital it states on there,
movements should not reduce, but feel more like rolls then kicks.
So I went in and the midwife there took one look at my bump and said "oh your small".
She had a look at my notes and noticed I had a growth scan at the beginning of the month and asked if I had another arranged. When I said I hadn't she booked one there and then.
My growth chart shows baby being just above the 10th centile line and measuring 2 weeks behind, and my bump started dropping on the chart.
So now I have a growth scan booked for Monday.
To say that I'm worried about it would be a understatement. I am bricking it.
I've noticed that my bump has seemed to slow down in growth. I weight myself this morning and have lost 1lb, could be my scales on the brink.
So this weekend is going to be a long one. Monday is going to be a decider of whether this baby will be arriving early I think.
From the start I have been worried about having another IUGR baby. But on the plus side we still have all our little boys old clothes. so we have nothing to get.
