Crown rump length and gender link

Looking through my notes and came across this chart online and found it interesting! So crl was 62.7mm and ga was 12 weeks and 4. So It would indicate a boy? (On this theory) Black line is boy grey is girl

So, when they were measuring the baby, on my scan, the date was going up as the measurement went up, when they drew the line. I thought they gave you a ga from the measurement, like a standard/average. Very intrigued if this actually does work. I need to find my notes and take a look!

Well i thought that to but when I looked online womens ga was the same as mine but differed crl so I was like hmm! Xxx

@Jess I had a private scan at 10+2 and then my NHS at 13+2, so I'm intrigued to see if they both hit the same line

I think my scan was 12 weeks and 4 too and I measured 6.4 so that’s interesting…
