We had a blood test done at 10 weeks and it said girl. Just had my 19 wk anatomy ultrasound and the tech said boy..?? I'm now shocked and confused. I was completely prepared for a girl and the dr said the test was probably just wrong..? Has this happened to anyone? Any chance they were just seeing the cord? Legs were crossed and covered the bum the whole time and baby wouldn't move them .. not sure if that makes a difference or not .. thanks!
