Went wonderful. The babies are "stacked" 1 on top of the other and measuring great with no markers! I understand that gender determination right now isn't 100% but I honestly believe we got some VERY obvious crotch shots. The tech was able to point out a vertical numb on baby A/bottom (measured 12w6d) and 3 lines on baby B/top (measured 12w3d).
Re: NT Scan this morning- AW
My scan is next week so I've been doing a little research on the possibility of gender determination as well! Someone here (maybe 1st Tri?) a couple of days ago posted a link to a site that discussed it with actual pictures. And from what that showed, I think a vertical "nub" meant girl and a "nub" inline with the spine meant boy. It was a super fascinating website!
ETA: I was backwards about the nubs! Here's the site.. https://www.baby2see.com/gender/external_genitals.html
