Tomorrow we leave to fly to anchorage for our level 2 ultrasound and amniocentesis.   At our 20 week u/s they discovered our little boy was missing a hand. Our panorama came back absolutely normal but it's been about 4-5 weeks since our last appt and the doctor discussed the possibilies of chromosomal anomalies and other health issues associated with a missing extremity. They decided it wasn't ABS which would have made it simple and not so complex.
