Lovemy4 - bright white line

Thank you so much for helping me to understand the nub theory better. I'm sure it will take a while till I can figure them all out like you can. Below are all confirmed boy nubs- which is why I was uncertain about the white line in that recent nub post. I have read that it can be the hip bone and not necessarily the nub. Is that not true? Thanks again for your help. I appreciate your expertness :)
I didn't draw those arrows, by the way:Attachment 6599

Attachment 6602

Intersting queston,im very curious to know this too x

I'm not whom you've asked but the spines are not straight in the lower pics you posted. Some are circled and at least one is arched...the first under the arrow one could be arched too- you actually cannot see the spine. It throws off the angle of the nub either way.

It does throw off the angle on those. But don't you think if lines were to be drawn it still wouldn't be more than 30 degrees.

Some of the pics also show a faint blob on top of the bright white line which is the boy nub hiding behind the white line part of the nub. sometimes the smallest of twist in baby can hide it. please look at my confirmed boy shots for some more examples :)

You definitely had a couple that looked girly. But you also had ones that were short and the blob bit was pretty pronounced. Interesting that yours are from the same baby!

Nbp- so if the baby isn't totally flat (spine) is a nub guess inaccurate?

I'm not a tech but I know that's what you look for to gauge the correct angle. An arched spine makes it point falsely downward. A curved spine, up.

That's why I feel iffy about mine still - I don't think it was laying exactly flat.

Ohhhh! Now I understand! Thank you! So if the spine is curved it's not very accurate?

I'm not quite sure on what you are asking. Those are tricky nubs in the pics you have posted--with some of them we aren't seeing the whole nub as baby is just a bit off center from capturing it completely. In others the back is a bit curved. I will admit that a couple I would have guessed girl for sure on but I don't know the gestation of all of them either and I don't knowingly guess before 12 weeks. Nubs start out flat for the most part and gradually angle up over the course of the 11th week and sometimes early into the 12 week so that could be the case in some images as well.
Really, the best way to learn is to keep guessing and asking questions :)

They were all between a little over 12 weeks and a little over 13 weeks.

I was asking if these were definitely the nubs or if it was at all possible that it was part of the hip bone (as some techs have stated). NBP helped me to understand better about the curled spine and how those aren't as accurate.

I dont think these pics are showing the hip bones, because they are really good profile shots, i think hip bones will look like nubs if the baby is rolling over kind of iykwim. Nub guessing is not 100% obviously it takes a very good shot of the nub at the right time to get a good view and then a good guess, some ladies are really lucky with the shots they get (usually when the tech is willing to get it) others are not the best and can go either way.

Thanks! All of this can get confusing. On another site, I've read that these white lines aren't the nub because they can be seen on either gender. So since these are boys- I just wanted to make sure that the white lines are the nubs and not a bone like others have suggested

Ahh okay :) Yes, these are nubs for sure--possibly not the entire nub on some of them, but definitely nubs and not hip bones.

Nub guessing is just not 100% , I think even with clear nubs and experience , my dr said its about 80%. And if you think about it 20% is still a lot of people whose nubs might not give them accurate guess.

Thanks everyone!

I think if it were in better focus when it is enlarged more people would have guessed boy. It has a knobby bit on the end.

Well now I'm more confused bc I just look for angle not knobby bits lol

I saw this illustration which I thought was interesting.

Oh interesting.

!

I did ask the tech at my nt scan about shape vs angle since they seemed familiar with nub theory and She said shape had nothing to do with it.. Just angle

jark-
