Sex guess from the CRL (crown rump length) at 12 weeks?

[CristinaNov182]

My baby measures 59.5mm at 12 weeks (adjusted to 12 + 3 based on measurement).

Just read males measure longer than females even at this stage. I can’t find a table that is per day and not per week, so I don’t know what to think? Looks like a small boy or a tall girl? :))

Im 5 feet, my DH is 6 feet, we have one DD that is smaller than average in height.

you can’t see the nub in any scan pics so I won’t bother uploading them.

we will get the nipt results in a week so will find out soon anyway but I’d like to have a look if anyone has a link to a table with measurements per week&day for CRL boys/girls

thank you

Oo so exciting! I have mine tomorrow! I’ve not heard that boys are longer before but thank you for the tip. Can they give you any indication of what they think it might be at 12 weeks or are they not supposed to invade they guess wrong?

What are nipt results?

see table 2 here for CRL pay gestational age and male/female correlation

obgyn.onlinelibrary.wiley.com/doi/10.1002/uog.1084

there is an overlap so I guess only for small or big measurements there is a clear sign

i get my nipt results next week

Nipt is a genetic screening test for genetic conditions like Down, edwards or patau syndromes.

Got high risk for down at my combined test, did the nipt after and today it came back low. While it’s not a diagnostic test, it’s very sensitive, picks up 99.99, so I’m happy I got a low risk 1:10000. I had the same situation with my DD and she as fine.

and btw it’s another girl! Haha taller/longer than average for her gestation age. There is an overlap in that table in the link I posted earlier.
