NIPT low fetal fraction

I had the Natera Panorama NIPT test at 11 weeks… 2.5 weeks later I finally found out that the results were inconclusive due to a low fetal fraction. I am panicking after googling and finding that this can sometimes mean that there is a higher risk for genetic abnormality. I just redid the test a few days ago at 14 weeks, but am freaking out that I will have to wait another 2 weeks and may end up with another inconclusive result. Has anyone had a similar experience?! Also, I just turned 35 last month, and this is my second pregnancy.
