TTCPink - I totally understand the family emphasizing gender...mine have done the same in the past. Not this time, though...I waited till we knew it was a boy before even telling them we were pregnant! Haha! But, in all seriousness, family's reactions make it sooo hard...I am so sorry you're dealing with this. :(
Bunny - I can't really zoom in, so I don't see anything, but if you see something, you never know! FWIW, I saw two small white lines on one of my little guys' pics, thought it could be the nub, but it was actually his spine. If the lines are lower, I would think spine, if they are higher, I would think possibly nub. :)
Merry Christmas, everyone!
