Self-made ultrasound at 16 weeks!

Hi, I am a pediatrician and did try to do an ultrasound on myself (with some watching colleagues) at 15+4 weeks for a potty shot of our third baby.
We already have a daughter and son, initially wanting to sway for a girl as our son has autism... but as we love our surprise baby we are really excited to find out what it is!
As we normally use the ultrasound differently I am not experienced with fetusses! Now we have three opinions- I thought the thing between the legs was the cord- one colleague said it SO looked like a penis with scrotum in the one pic (she has a point), two others said "not enough evidence" to decide ;-)

What do you think? We have no nub shot from our (expert) scan at 12+4, only this potty shot. Attachment 41406

The links did stop working for me- so here the pictures in-line:

Nub shots at 12 weeks and sadly even into 16 week range are not as reliable as we would like.

My guess is girl and I think the "penis-y" thing is cord as it's way too long to be a penis. BUT the next to the last pic is a little iffy for me, could indeed be penis - just depends on where the wand was focused. I'm sorry I can't be more help, it's just that the 12 week for sure, and even the 16 week potty shots can be confusing and I don't like giving incorrect replies when I'm anything than 100% sure.

I hope you get what you're wishing for!

The first pic had me thinking girl but middle pic (second from bottom) makes me think boy. Scan again but put a small box of color on to rule out cord vs. penis. If it's cord it will light up from bloodflow.

Thank you so much for your guesses!
2blue1pink: I too thought about putting a color box on it- but in the end did not like the high energy doppler just to guess..
I did another quick scan at 17+3 weeks a few days ago and could not see any boy parts- even found three white lines in one shot! So I thought 99% girl, we´re so excited! :running:
