13 Week scan - Potty Shot - Nub?

I had my 13 week NT scan done a few weeks ago and the sonographer told us the gender, He was 80% certain he seen "boy's appendage"

I'm not fussed by the gender but I'm a little annoyed he told us so early as I know it's not always accurate, especially from a "Potty Shot"

This is the profile shot - Not clear and I cannot see a Nub.

Is this the nub or too low to be a nub?

Wow. This is tough. On the gender video, 7 seconds in, I could guess boy off that. However, I can't find the nub in any of your pics. And if I hadn't seen the gender video and just looked for a nub I probably would have guessed girl.

I'm not sure on this.

What did you see 7 seconds in that could make you think
Boy? I've watched it over and over again and can't work it out. I still have 4 weeks until my
20 week scan and it's driving me insane lol. From what I understand a potty shot at 13 weeks isn't very accurate? And the angle it's taken from seems to be a lot of babies back showing not just the bottom, legs and genitals? I'm no expert but 80% from the sonographer has me thinking...

A boy's appendage.

I thought they all had a protrusion at this gestation? I'm temped to get a gender scan done but all the clinics are 2+hrs away.
