Are ultrasounds usually 100% accurate?

while ultrasounds are 80-90% accurate, they are far more reliable than determining the sex by "the way you are carrying". Thats just old wives tales. Nothing in medicine is 100%, but 80-90% is pretty darn close. You're most likely having a girl. Congrats!

The way you're carrying is an old wives' tale as far as whether or not it's a boy or a girl. It has more to do with how the baby is lying, your own anatomy (how your muscles are, your posture, your height and weight, etc.).

However, ultrasounds are NOT 100% accurate in telling the sex of the baby. They are very good by around 20-22 weeks as long as the baby is in position for the technician or doctor to see their little boy or girl parts, but they are definitely not foolproof. And they are very often not accurate at all earlier on. A friend of mine was told with a high degree of certainty that she was having a girl at her nuchal scan (12 weeks), and at her 20 week scan they told her just kidding, it's a boy!

I would think it's probably pretty safe to assume you're having a girl if you had a good tech or doctor tell you that was what it looked like at 22 weeks. If you would feel better, see if you can get them to agree to do another ultrasound closer to the beginning of the third trimester to confirm. I'm running on the assumption that the regular ultrasound I had in the office, followed 10 days later by a detailed 20-week scan, both are right and that I'm having a boy! But I'm doing our nursery on the more gender-neutral side anyway, so worse comes to worst, it's not a strongly boy-type nursery if we get a surprise when I deliver and it turns out to be a girl. :)

Good luck!

The way a woman carries really depends on her body type. It is a common misconception and an old wives tale that babies carried low are boys and high-carried babies are girls. It all depends on your body type, whether or not it's your first, if you've dropped, etc. People will listen to anything and adhere to those wives tales as if absolute truth. It can actually be annoying (I am pregnant with #2) when you have people tell you things all the time that you simply know otherwise about... I get it all the time and while I usually just smile and nod sometimes I can't resist letting them know the truth, lol, hormones!

When I had my first I wanted her to be a girl, too. The scan revealed a girl and though they said they were 99.9% sure I still worried, obviously, from hearing about people who had the opposite. I had another scan and they did confirm that she's a girl so yeah, mine were right. Did they point out the genitalia to you, what did it look like? That's another help... the female parts generally look like three lines on a scan...

Good luck! =D

Ultrasounds don't lie. BUT the technicians may not see things correctly, etc. However, I would trust the ultrasound you had over the way you carry. That's a old wives tale that has no proof to it at all and can be very wrong. You have a 50% change of being right if you just go by that, and 50% to be wrong. Total luck if people get a certain gender from the way they carry. I'd say congrats on the baby girl!

Ultrasounds can't be 100% accurate for the sex of a baby because the penis or testicles may be hidden. Or the umblilical chord or something else may look like a penis. It is the best way to tell the sex though. And it is probably more accurate on the other things because those are tested in a different way. With measurments of the body part or other more accurate ways. The sex is determined just by what the person giving the ultrasound sees. Hope this helps.

They aren't 100% accurate, but they are pretty accurate. There have been times when they've been wrong though.

By the way I'm also having a girl, I found out at 21 wks and 3 days and I'm now 38 wks and 4 days along. I also have a couple people ask if I'm having a boy because of the way I'm carrying, but I've already dropped, my daughter is very low and so that makes people think I'm having a boy, because the old midwives tales say if carry low it's a boy, if you carry high its a girl. I was carrying high, until she dropped.

They are between 95% to 100% accurate. If it is misread there is a higher percentage of boys being misread as girls because sometimes the tech will assume girl if they can't find a penis. If your tech saw the three lines that indicate girl there is no doubt that it's a girl.

The way your carrying has nothing to do with the gender of the baby, it's an old wifes tale.

The ultrasound is a machine. Unless it is faulty, it does exactly what it was designed to do - send ultrasonic waves through a medium and deliver an image of what is inside or beyond that medium to a monitor. The error is usually that of the technician, but sometimes it isn't fault or error, but rather that the baby's sex is not reliably visible for long enough to make a determination. That's why you get stuff like, "I'm about 85% sure it's a girl..." or whatever.

It's not 100% but the way your carrying has nothing to do with gender everyone says oh you look like you are having a girl and I am not At my 20 week scan we saw boy parts and they were unmistakable... The way you carry has nothing to do with gender! Congrats on your little girl...

No. They are dependant on the baby's developmental stage and position and the best guesstimate of the person viewing it. They told me my second son was a girl up until 3 days before birth, simply because his "boyparts" were in shadow. A coworker had the same thing happen - except she didn't find out until the delivery that her baby girl was a boy - and she already had the room painted pink and purple!
