Help with Ultrasound Pic - No lines, no turtle!

Had an elective US yesterday at exactly 15 weeks and tech was confident it's a girl. Although I definitely don't see boy parts, I would like clarification on how this is 100% girl parts. I see no lines whatsoever, more of a v shape. It is also such a pronounced white mass between the not too open legs and I've never seen that on a girl US. With my 4 year old daughter, the white lines were very visible. I'd just like to know why it is 100% a girl. Thanks!Attachment 35509

That's definitely a girl! Congrats [emoji175]!

There is no visible penis or scrotum. What is shown is the labia- the white parts shown.

Thank you! I've just never seen any US pic that looked like this, girl or boy lol. We're very excited as our daughter wants to have a sister so badly!
