I went for my 14 weeks scan today. I am having ID twins and so am being scanned more regularly.
They told us the one twin is smaller than the other. It is not TTS they have confirmed. They then proceeded to tell us what would happen if the smaller twin continued not to grow.
Both babies were within the normal range for my dates 15 weeks, the larger one is in fact at the top of the growth scale.
They were both really active on the scan and they have equal amounts of fluid around them, they are in seperate sacks. But the hospital have made me feel scared and worried..
I have posted on the multiple births thread, As of yet no one has got back and im sitting here freaking myself out that something is going to go wrong... 
Just asssumed because they are identical they would be exactly the same ..am I overreacting? feel really deflated...
