NIPT- x3

I took my first NIPT (Natera Panorama) at 9w6d and it came back 12 days later "couldn't yield results due to low Fetal Fraction" my FF was 2.8%. My doctor had me take the test again at 11w6d and my results came back again the same but my fetal fraction was 1.8%, so it went down. My doctor has me taking it one more time, this Wednesday, I'll be 13w6d, and if it comes back the same he is sending me to MFM.

I'm just so nervous and looking for women with similar experiences and what your outcome was.
