Can you help me to find the nub?

Hi!
I''m so confused about my ultrasound that I'm not even trying to guess if it's a boy or a girl. I simply can't find the nub! I uploaded my video on YouTube because I couldn't take any screenshot showing properly a nub image. Could you help me?
Baby's position turns easier to see at 4:50, before it he/she is kind of "head over heels".
Thank you so much if you can help me!

Think it looks flat so maybe a girl.. could only see the nub briefly though right at the end of the video

Thank you so much for your reply, I'll try to look again at the end of the video, thanks for the tip!
