Nuchal Measurement

[osmo18]

Hello, I had my scan this morning and was given a nuchal translucency measurement of 0.9, the sonographer or midwife didn't really explain anything other than them stating the number 0.9. I've tried googling but can't really get an answer, is this a high low or normal measurement for 13 weeks?

It’s low and good sign of health.

From what I gather that's slightly low but I'm not sure if that's a problem or not. I think only high measurement would indicates a possibility of Down syndrome?

I measured 13 weeks today and my measurement was 1.9mm which was confirmed as "within the healthy range".

Did you actually measure 13 weeks or could you be earlier?
