Panorama test at 12w2d came back "no result" - fetal fraction only 1%, so not enough DNA in my blood for the test to get a result. I'm 104 lbs and 5'2" so it's not a matter of being overweight. Has anyone else had this, and in the end what were your results? Worried because I read that a low fetal fraction is associated with high chance of genetic abnormalities. I also never had any morning sickness throughout the pregnancy. NT scan and the anatomy was checked at 12w2d and both were fine.
