Gender question...

Anna

So at my nt ultrasound at 12w6d I asked the tech and she said it looked like a girl hands down- I saw it too; flat as a board between its legs. So today at 13w6d I went to a place where you can pay to find out gender cause I wanted a pic to tell people with and she said 99% boy! She had a SUPER hard time getting this pic because it wouldn’t spread it’s legs, but I’m wondering if she’s wrong cause it looks dense like the leg bone so maybe it’s cord??? What do you think?
