Nub guesses?

babyferg11

This was from my NT scan yesterday at 12w4d. This is my second baby. I see the nub in a couple of pics (I think?!), but I also see an area above the nub that I'm not sure is part of it?!? I've attached all of the pics from my scan. I'll be curious to see what peope think!

 

I know the nub theory is just a guess, but some feel it's pretty reliable!

 

Thanks in advance for taking a peek at my guy or gal!
