Usually 18 weeks by us is the earliest they would confirm…

My doctor advised that you can pay for an early ultrasound at 15 weeks to cofirm the sex or you can wait to your 18-20 week appointment.

Depends.  My mom had an amnio (genetic testing) done around 11 weeks and she knew it was a girl when the report came in.  Otherwise it typically takes until week 14+ for the US tech to see gentalia on the monitor and most won’t even make a guess until 18+ weeks because the genetalia looks pretty similar until around that time when the little boy parts start really looking like a penis and scrotum.

When we did our Nuchal Translucency test to screen for risk factors for Down’s Syndrome and a few other chromosomal abnormalities, the doctor told us it was a girl. I was 13 weeks and 5 days. It was confirmed at our anatomy scan at 18 weeks, 5 days.

I personally wouldnt trust results any earlier than about 15 weeks. Some places say they can do it sooner, but I’ve heard of way too many people being told one thing and the baby ending up being the opposite..

I wouldn’t trust the results at the 12 week ultrasounds. So many are told boy or girl, but then at the 20 week ultrasound they find out the original “guess” was wrong. I would wait until the 20 week ultrasound (at least 18 weeks generally) to be sure!

@Irish-bride:  I knew at 12+4 (NT scan) that we’re having a girl. It was confirmed at my 20 week US.

BabyBond is a company in the UK that does it at 16 weeks. We went to the one in Cambridge at 16 weeks 4 days.


It costs £79 and was worth every penny. The tech spent about an hour letting us look and gave us a whole envelope of pictures, including a couple 4D ones for no extra charge.

There is now a blood test at 9 weeks that can confirm sex.

@Irish-bride:  Yeah, I definitely undestand that. I had my regular scans on the base here and was only transferred onto the NHS at 36 weeks. I would assume they will do a scan between 18-22 weeks? You should find out then.

The closer you wait until 20 weeks the more accurate it will be.  I had a friend recently who had the early ultrasound and they told her a girl. At the 20 week ultrasound they said a boy.  It was a boy.  To me why waste the money on an extra ultrasound that may or may not be accurate.  I too had a friend who did the blood test at 16 weeks to test for Downs etc.  And their test came back with a girl.  However, they said it was really losy way to get the results because their’s were given to them over the phone by a computer.  So not very exciting.
