How many weeks was your sis when she had her 3D, I would like to get that one done too but its not covered by insurance so will have to find out the cost and also the reason for getting it!!
My US is on July 2nd...thanks and good luck to you as well.
I am going for my ultrasound on June 29th!!!!!! Can't wait. Good luck with your ultrasound. I think I am going to get a 3D ultrasound later on then. My sister had one with her first baby and it was just amazing. You could see she had big puffy cheeks already which she did when she was born (and still does).
