I am 25 years old and had my blood work which came back negative for Down Syndrome and other typical chromosomal abnormalities. But when I got my 12 week ultrasound they say the fluid behind the head is measuring at 5-6mm and should be less than 3.5mm. Now they are making me run extra test and see a geneticist. Anyone else have anything like this?
