Help guessing the gender of my baby!

I would love it if you guys could help me predict the gender of the little one in my belly. ;)
It's from an ultrasound in week 13. Heart rate 164.
Is it the nub that looks like a wrench?

I'd guess boy

I'm not sure about this one. It looks slightly boyish, but for 13 weeks and an arched back, it could be girl. I'll give a slight girly lean.

Yeah, I'm honestly not very sure of my boy guess at all but that's what I was leaning at first glance. Tough one.

Agreeing aswell, tricky!:) The boyish nub bit just looks too far up the body, cord maybe?? Leaning girl also:)

How interesting! :)
Thank you for your thoughts!
Please feel free to keep on guessing!

I think boy. Looks a bit short and thick for a girl but could maybe be cord.

I am a bit confused about which part actually is the nub. As Babygirlquest says, it looks a bit thick to be the nub, maybe it's the cord? I zoomed in the two pictures and marked the nub/cord with a 1, and if you campare the two pictures, it really looks more like the cord. So maybe it's the nub marked with a '?' ?Attachment 28812

the nub is at the 1 :)
