And, Sunshine, they didn't tell me about any of the other soft markers so I don't know what any of the others are. I do know that they looked for symmetry between the two halves of the brain, the length of the limbs -looking for a short femur or humerus, they check the circumference of the head and stomach, they check the nt fold again, the nasal bone, they look for a cleft lip/palate.
Don't know if any of this helps.
The amnio was a little nerve racking. It was short but felt like a long time. They took two vials of fluid and I remember them telling me, "Take a breath" because I was holding mine as I watch the needle go in on the ultrasound screen. And it's Friday the 13th, no less.
