Panorama says girl, 3d ultrasound umbilical cord?

Hey everyone! So I went for a 3d ultrasound the other day just to see the baby bc I haven't since my 6 week scan, I'm now 14weeks, I told them not to look for the gender bc I already knew it was girl from panorama blood test and I had family with me (we're announcing it next Saturday at a gender reveal). She said she's always careful not to take any video or pictures that would give the gender away, well my dad saw two pictures/positions on the live video and he's convinced it's a boy but the technician laughed and said that's the umbilical cord and that the blood test is more accurate than the ultrasound at 14 weeks which is why the soonest they will do a anatomy scan is 15 weeks. She said she was being honest that it's the umbilical cord but now everyone who sees that picture says boy lol it'll be a nice shocker for them on Saturday but I just wanted to get your opinions, that IS the umbilical cord right?
