Has anyone else experienced this at their 12 week scan? The measurement is apparently accepted at 3.5mm or below and mine was 3.9mm. We have been referred to a specialist unit at another hospital next week but I'm naturally now worrying myself sick!!
My consultant mentioned the risk of chromosomal abnormalities but they won't know the full picture until my blood test results come back and I get a more detailed scan done at the specialist unit.
Thanks x
