We didn't get it, but no, I didn't regret it at all. We won't opt to get it next time either. My feeling was that it didn't give me any useful information that I could do anything with. Our daughter was born perfectly healthy, but if she had in fact had any chromosomal abnormalities that led to a problem with her development (like a heart abnormality), that would have been picked up in the 20 week scan and we could have investigated that further then. We had a home birth, so if there were any issues that would have led to needing a higher level of care, I would have wanted to know that and that would have shown up in the anomaly scan. I didn't really think it was useful to know what my statistical risk of a chromosomal abnormality (which is what the NT scan tells you) was in the absence of an actual issue with fetal development (which is what the 20 week scan tells you). We wouldn't have opted to end the pregnancy under any circumstances and I wouldn't have done anything different in terms of my pregnancy and birth unless there was an actual issue detected later. In my case, it just seemed like an extra thing to worry about, plus a waste of resources to do (costs the NHS money, but wouldn't have influenced my decision-making anyway).
