No three lines, I don't think. But nothing to indicate a boy! If my midwife calls and says it's a boy, I will poop my pants. I would have no idea what she saw to indicate a boy. I saw nothing between the legs at any point. And like I said, she held it there for some time as she measured the legs.
******NOT MY PICTURE******
This is exactly what I saw, minus where it says 'girl' lol :

I have a private ultrasound on the 26th to confirm! Since although I saw, I want to see while someone says "LOOK IT'S A GIRL" lol. I still can't be sure just yet!
