3 Lines Girl Ultrasound Do Babies Know What You Are Having
"The commonest and most reliable way to determine a baby's sex during pregnancy is during an ultrasound browse, usually performed from 18-21 weeks on the NHS.
"During this ultrasound scan, sonographers are looking for the distinguishing signs of the different ballocks.
"With a female baby this can appear to wait similar 3 white lines. With a male baby, information technology is often possible to observe the penis, testicles and scrotum at the second trimester routine scan."
What are the iii lines on an ultrasound?
"Looking for the 3 lines is one of the ways that we are able to decide if you are having a girl," agrees sonographer Jan Steward, Manager of Ultrasound Straight.
"We give all our parents that come up for scans some instance 'potty shot' photographs of what we are looking for when we make up one's mind sex.
3 lines – daughter example
"The flick below is of a 20-week scan of a girl and clearly shows the iii lines.
"When the sonographer points out why she thinks it is a girl she will apply these 3 lines as an illustration."
And hopefully this will exist conspicuously seen on the screen when you lot're having the scan.
Lots of the mums on our forum have experienced sonographers using this method when they have scanned them. As fall3n-ang3ltold us: "When I was having twins I was having a boy and a daughter.
"The daughter has 3 lines and when the sonographer showed us you really could tell the difference."
three lines – boy case
This twenty-week scan, posted past forum user SW2, shows a boy. Information technology looks very different from the iii lines girl scan above, with the genitalia clearly sticking out.

How accurate is the 3 lines ultrasound method?
It's not ever right, says Professor Lees. "Even during the 2nd trimester routine browse it may not exist possible to exist fully certain most the babe'southward sex because south/he may be in a position that will make it difficult for the sonographer to be certain."
Indeed, every bit the Professor says, as with nearly things in pregnancy, it's never entirely anticipated. Only, having spoken to sonographers, we think identifying the 3 lines is a pretty safety bet on yous having a girl.
That said while the iii lines is definitely a tried and tested method, sonographers themselves will e'er exist aniggling chip cautious.
"Fifty-fifty if the three lines are identified it is nevertheless only an opinion from the sonographer," says Nigel Thomson, Professional Officer at Ultrasound, "albeit a reasonably accurate 1."

Thou Lou, however, found that her sonographer at a private scan was happy to exist pretty definitive.
"I had a private scan at 16 weeks and I was told I was having a girl. She said she would eat her hat if information technology was a male child and showed me the 3 lines."
Though Jan agrees with Nigel, saying: "We give a professional opinion but there are a few cases when at that place is a surprise. There is no such thing as 100 percentage."
At what age/stage tin can you come across the three lines on an ultrasound?
Within the NHS this method is generally used every bit part of determining sex at the scan everyone is offered at around 20 weeks. At private clinics it is usually used every bit a method from sixteen weeks.
"The iii lines are visible from 16 weeks because the baby hasn't got whatsoever muscle or fat deposits," explains Jan.
"As the pregnancy progresses and the baby becomes chubbier, the labia begins to swell and the same 3 lines nosotros meet at 16 weeks now smashing up from the mid-trimester onwards.
"It can then become more hard to exist sure because if a little boy has his legs together the testicles can go squeezed and look similar. It is definitely easier to tell earlier on in a pregnancy than after."
On our forum, HappytoHook shares her experience of the iii lines method at around xx weeks.
"She sexed the baby for us, describing what she could see and checked 3 times! Three little lines of the girly bits – a hamburger she called it! She wriggled infant a bit to brand sure no boy bits were hiding!"
Tin y'all see the iii lines on a 3D/4D scan?
As a general rule sonographer's volition not use 3D/4D scans for sexing your baby. This is mainly due to these scans being done much after in pregnancy when information technology's harder to tell.
As Jan explains: "Despite popular belief information technology is a lot harder to tell the sex activity on a 3D or 4D scan. 4D is dependent on foetal position and amniotic volume.
"Besides, at the optimum fourth dimension for 4D at 28 weeks, the genitalia tin be difficult to visualise."
Will I ever be able to see the 3 lines?
"Information technology is non always possible to come across these 3 lines," warns Nigel. "The position of your infant is obviously a cistron. If they are conspicuously visible, notwithstanding, it is a expert way to determine sex."
And while the sonographer might be using information technology as a method to cheque, those 3 lines might not be immediately obvious to yous. Certainly non perhaps as clear as boy bits!
Lynz_81 shares her advice: "Try to accept a good look between the legs. Boys are unremarkably pretty easy to see, my 2 looked like little snails."
Will I see the 3 lines on the scan picture after?
In some cases you may get quite a clear illustration of the 3 lines, non and so much in others.
For some of our mums, even when it was blatantly obvious in the scan room that they were having a male child, with a willy clearly showing, it didn't come out on the picture at all.
"We wanted to know the sex of our baby and in that location was no mistaking our strapping young man in the scan room," says snappyloz on our forum. "I said information technology to them before they said information technology to me, but there was no sign of it on the picture."
