Q&A: I am having a stage two ultrasound instead of amino and I don't know why.
What is a Stage 2 Ultrasound? What will it show, since I am having this instead of amnio?
Stage 2 is more detailed than stage 1, getting into more specific screening techniques, like heart chambers, cord anatomy, etc. Stage 3 is the most detailed, reserved for suspicious conditions that would put your pregnancy at high risk.
Stage 1 is just a screening ultrasound.
