Were you ever surprised at the gender of your baby because you were told it was a boy, but it ended up being a girl? Or the other way around?
We were told our child is a little girl, but my darling partner brought up “Wouldn’t we be surprised if his “thing” was hiding?” Lol does that REALLY ever happen?
I was told my daughter was a girl and she was.
I have a friend who was told she was going to be having her third girl but at birth, they found out it was a boy! I think I read somewhere that it’s more common for people to have an “oops surprise boy” than an “oops surprise girl”. I do believe blade is the resident doctor. I hope she can give us some facts. 
I was originally told that they couldn’t tell what I was having because of the way the baby was lying, and then I was told it was boy and then I was told it was a girl. That was my first child who was a girl in the end…
I’m now pregnant with my second baby and I have been told from the start that she is a girl, I was kind of hoping for a boy as I’ve still got some random boy stuff around the house that I couldn’t give away to family or friends with sons or who were expecting sons.
But I’m happy with my little girl and her little sister who is going to be joining us very soon!
I don’t know of anybody who was surprised at birth, but I know 3-4 couples who were told they were having a certain gender around 18-20 weeks, but then it was reversed a few months later. One that was told it was a boy fully decked out a nursery full of typical “boy stuff”…trains, cars, etc. only to be told (literally a week after completing the nursery) that they were actually having a girl. At least they still had a month or 2 to switch things around, ha!
A friend of mine was told she’d be having her fourth boy…only to hear “It’s a girl!” in the delivery room…she was super shocked and thrilled.
I think [name_m]Blade[/name_m] has said before that if they tell you it’s a boy, then it’s a boy. The mix ups are usually when they say it’s a girl and you have a boy instead. Although I believe mix ups are pretty rare these days.
[name_f]My[/name_f] parents could not find out the sex for my sister or I as we were too large (it was the 1990’s, not sure if that says anything), but the hints were dropped to say that I was a boy. I can safely confirm that I am not a boy, nor have I ever been :p. I’m sure it can happen, but I’m not sure it’s common. I’m guessing it’s more likely to happen than say, not knowing you were ever pregnant until birth, or having surprise multiples, but other than that I don’t know.
I think if they can’t tell FOR SURE they just don’t tell you (or they SHOULDN’T anyway). I know a couple people who have been told wrong - one for each gender.The 3D ultrasounds are extremely accurate, I’ve never heard of a 3D gender scan being wrong.
[name_f]My[/name_f] mom’s friend was told she was having a girl, but she actually had a baby with ambiguous genetalia, and he is a four year old boy now. When I went in for my anatomy scan and they said the baby was most likely a girl but they were having a hard time seeing the labia, I was legitimately worried my baby had ambiguous genetalia. Thankfully in a few weeks they confirmed the presence of female genetalia. So… There’s a probably previously unconsidered third option for you to ponder. Sorry!
Interesting thread.
A friend of mine was told she was having a girl, and then in a late term ultrasound (sadly when they couldn’t find the heartbeat 
) they found out their little girl would have been a son.
I’m honestly curious as to what I’m carrying. The sonographer told us “it’s not a boy” but didn’t show us those tell-tale three white lines, and didn’t come across very competent with the ultrasound over-all, so I’m not sure I believe him. Either way, I’m having a baby, so I don’t really care 
Yes, I have some friends who were told they were having a girl, and then they had a boy. I’ve heard of a couple other people who have had this happen, so it’s not uncommon to think you’re going to have a girl and have a boy instead. I’d have a back up boy name on hand just in case.
The opposite happened with my sister 10 years ago. At the 14 week ultrasound they said she was probably a boy, but it was really to early to tell for sure. She never cooperated at during the other ultrasounds for us to really know what she was, so while there was a good chance she was a boy we never really got a definite prediction.
[name_f]My[/name_f] friend’s parents were told they were having a boy and then in the delivery room she turned out to be a girl! I think Ultrasounds are pretty accurate, but there are certainly cases where they don’t work.
I know somebody who was told it was a girl at one ultrasound then a boy at the next. It was a boy. We had the ultrasound tech guess at around 13 weeks and both times they guessed correctly. We waited until 20 weeks though to really believe it was a boy or a girl. I was convinced my daughter was going to be a boy pretty much the entire pregnancy but that was just in my head. I even packed a neutral outfit to bring her home incase the dress my [name_f]MIL[/name_f] made wasn’t appropriate.
I think that it is most likely to happen if you don’t have very many ultrasounds. Some doctors order more than others, some insurance companies cover ultrasounds than others. [name_f]My[/name_f] sister’s last pregnancy was high risk and she had an ultrasound every week or so b.c of concerns about the placenta. So if you just get one early one, the baby might not cooperate and the tech might be wrong. BUT if you have loads of them (which many people do) or have one later in the pregnancy, they are really good nowadays and they are unlikely to be wrong about the sex.
I have wondered about the same thing, and I found a research article that studied how accurate these scans are. In this study, they looked at what ultrasound techs predicted the gender was a 17 weeks vs. what the baby actually was at birth: The accuracy of 2D ultrasound prenatal sex determination - PMC
Out of 205 pregnant woman, all fetuses that were predicted to be boys were actually boys, but 2 fetuses that were predicted to be girls ended up being boys. So pretty accurate, but not 100% fool proof! Interestingly, the article also talks about how 3-D ultrasounds have not been shown to be any more accurate.
