I'd expect that a skilled ultrasound tech would be able to see things just as well on the 2D than on the 3D, but it might be easier for a layperson to understand a 3D model.

I think a lot of it just has to do with how the baby is positioned and how active they are. They had a heck of a time getting a good shot of the nasal bone when I went in for the nuchal translucency screening.

Good to know.  Thanks! :)

Because I promised I'd share this, I figured this was the best place. :)

http://youtu.be/0e_HF-Bc8mI A quick video of my ultrasound. :D

OH MY GOSH!!!!!!!!!!!!!!  Thank you so much for sharing Jynx!!!  Oh this really warms my heart... I can't believe I have one of those in my belly, too!!  Seriously, I can't thank you enough for sharing that.  So precious!  Your baby looks great!!

[JynxGirl]

My pleasure!!! I am still so happy that she let me take this video!

[BubbleMa]

I finally had a prenatal visit and got to see him/her yesterday. S/he was so wiggly!  Now they are saying my due date is May 19.  The heartbeat was 146 nd they could see the hemmorhage from last month.  It was so good to see those kicky little legs!

Actually, a 12 or 13 week fetus does not have fully formed genitalia, and you can't tell if it's a male or female by seeing if something is dangling between the legs - in fact, a something hanging down would be more likely to be a female at this point. At this stage of development, both sexes have a genital tubercle. The only difference is in the angle at which it points. The female tubercle is more in line with the spin, pointing down. The male tubercle is pointing more, well, up - just more towards the belly. There's a really good explanation here, with pictures and everything, just scroll down: http://www.baby2see.com/gender/external_genitals.html Note that the pictures at the very bottom are of a 12 week old fetus - 14 weeks pregnant, not 12 weeks pregnant. There are definite differences at that stage, but they are much too tiny to be seen on ultrasound. The only way you can tell at that stage is by the angle.

Then this page on that site actually gives a summary of a study on predicting gender using the angle (since you can't do it based on other features at that point, although you probably could if you had the fetus in your hand - just not with u/s): http://www.baby2see.com/gender/study_ultrasound.html

Anyway, interesting stuff, but don't get your hopes up for a boy if something is pointing downward right now. lol Honestly though, I can't see it. I keep looking, but I don't see it. Now I'm going to go look again. :)

Hmmm.  I believe you.  But, somehow that tech was right at 13 weeks...

And, her u/s picture has been zoomed in since this discussion began.  I can't see anymore either.

Because you can tell the gender at that stage, if you can get a good shot of the angle of the tubercle, just not by the existence of a penisy looking thing. :D If you read the links and look at the pics, you'll see what I'm talking about. If the tech was guessing based on what appeared to be a penis, rather than the angle of the tubercle, then they just got lucky. They got mine wrong at 14 weeks, telling me dd1 was a boy.

Oh, wow I just watched your video Jynx! That is so cute!

The place where we get Ultrasounds is great- very environmentally friendly & they never print anything. They email pictures of the ultrasound after the session. Well, we didn't want to know the gender but they emailed us some pics after our session and we just looked at them...it's a girl!!! I mean, I'm 99% sure. It's a shot of baby with her legs up and clear labia... I googled baby girl ultrasounds and it looks JUST like them. I'm on my phone now but when I get home I'll post a pic & you ladies can weigh in. I've only had boys, so I am curious to hear what mamas of girls think when they see it!

So exciting!!  :)

[janellody]

Ohh so excited to see meredith!!!!  YAY A GIRL!

[MeredithA]

So, here is my "gender reveal" ultrasound. Not the most flattering picture of my baby, as her head looks like an alien, but I am pretty sure that this is a clear shot of her girlie parts. I suspected a girl already, but when the tech emailed me this photo,  was like wow- there it is! A girl!!!! What do you ladies think? Should I go ahead and start knitting a pink hat? 

[MeredithA]

Cute little profile shot from today's ultrasound <3

[LinnieThree]

Totally a girl!!!!!!!!!!!!

[Kamiro]

Meredith, that totally looks like how all of my girls did. LOL

Congratulations!!!

[BubbleMa]

Meredith, are you going to tell hubby or keep it a secret?  :)

[MeredithA]

Rrrr I keep trying to reply to posts and when I hit "submit" it just deletes it and doesn't post it! 

Sarah, Hubby knows! He was looking at the ultrasound pics with me and actually noticed it first. I tried to be comforting and casual and just say "Hun, that's just our guess - we don't know for sure", but both of us know that those lines look awfully girly. So, hubby is disappointed. Not about it being a girl, but about his lost opportunity to discover the gender for himself at the birth. If he hadn't noticed it, I would have totally kept it a secret so he could have his surprise in May :-) 

[MeredithA]

Now I can't wait to see other ultrasounds of people having girls so I can compare!! Onemore, it is nice to know that your girls looked like that too. Makes me feel confident in knitting this purple and pink hat I've just started..
