Please help me!!!

So I went for a 17 weeks ultrasound today and the technician was so sure it's a boy but I couldn't tell and she couldn't get a good picture for me because of the way baby kept moving and the placement of the umbilical cord. I have two pictures and would love input! I have a daughter and I do definitely think their ultrasound pictures look different but I'm still unsure! Attachment 33262Attachment 33263

It's not very clear so I'm not sure. My son was very obvious at his gender scan at 16wks.

Do you have another scan coming soon? I would suggest you try to get a better look.
