UPDATED: Nub theory

[andthentherewere10]

So, what do you guys think of the nub theory?

If you are further along and did the nub theory, did you confirm it at the a/s? 

Brought to you by my 12week NT scan and super excitement over guessing the sex.

ETA: not sure I drew the lines appropriate...I feel like the line for the back may be off..

UPDATE: So, it looks like to me that the nub is more parallel with the back than pointing up, indicating girl.  I can't be sure that what is pointed out in the scan above, though, is the true nub, but if it is then the nub theory predicted girl.

We are having a boy!    So, nub theory was wrong???

From my bump month board, it seemed to be really accurate when the tech made a guess based on the angle of the nub. Mine wouldn't try though

I have never heard of this.

Someone on my BMB had a great nub shot and it was fairly easy to guess correctly. She had it confirmed at her a/s.

I actually think boy based on yours but it's hard to tell because of baby's position.

The doctor was right at my NT scan too. I couldn't really make sense of the ultrasound pic to tell what he was looking at though!

Hmmm, I never knew about this.

I will always think of stella on ML when I hear these theories.

Speculate all you want, but wait for DNA evidence or at least a later ultrasound before buying anything :-)

If your baby doesn't move around enough to open its legs at the 12 wk ultrasound to get this shot, you won't be seeing any nubs. That's what happened at my visit. My MFM even patiently waited a few more minutes but the baby's legs didn't budge.

I wouldn't buy anything yet but the tech guessed right with our first two girls at the NT scan. They guessed girl again this time, which is likely but we are waiting confirmation at the a/s.

My OB told me it's not accurate, but it's still fun to guess! The 20 week u/s was more reassuring (and confirmed my own NT scan nub guess for my little girl btw).

With your pics, I'd guess boy.

I believe in it. Google "in gender ultrasound prediction" and "babycenter ultrasound board." Both boards have real techs that look and make a guess on the nub. You will have to specifically call Turtle, the tech, out on babycenter to get her guess.

Yours looks boy, IMO.

I let my tech take her best guess because we were getting the DNA results from Mat21 anyhow. She was correct and looking back at it if she was looking at what I thought she was then it was no contest as his nub was completely perpendicular to the spine. Where in OPs pictures the same spot looks very parallel, but again I'm not certain that I was even looking at the correct thing. Important to remember is that the umbilical cord is only slightly higher up so that makes it even more difficult if you're not a pro at interpreting ultrasounds.

They guessed boy for us at 13 weeks based on nub theory. We find out Monday for sure, so I'll be sure to update.

[snickers]

I dunno where the nub even is in my ul;ultrasound pics, so I dunno lol

[jennifertx]

Nub theory was correct for us. Confirmed today that we are having a baby boy!

updated in OP

[shelbyann]

Congrats on your boy!

[Wonderwall]

Never heard of this...

There's a pin going around on Pinterest that says you can tell by your earliest ultra sound based on what side the placenta is on. Weird right? Let me see if I can find the pin to link...

[papie]

I shall update my post in this thread to say that it was wrong for us too this time, we are having a boy. So 2/3 success rate in our case, lol

[eav2c]

Yours looked boy to me from the start Congrats!
