Increased NT

Hi everyone. Really glad to have found this group. We had our 12w US and were so happy and excited to see our beautiful baby. Only to be told we were high risk for defects with an NT of 3.2mm. The tech had a REALLY hard time getting the baby positioned for images. Could that play into this at all?

We also conceived via IVF and had CCS genetic testing done on our embryos, does that lower risk at all? Terrified, confused, and stressed. Any words of wisdom are welcome.
