Low fetal fraction?

Katarina

We did IVF with PGS and my Natera NIPT came back as low fetal fraction. (Done at 10w6d)

I am supposed to repeat the test next week(I’ll be 14 weeks) but in the meantime I am freaking out because their algorithm put me in high risk for Trisomy 13&18.

Anyone had similar situation and everything was ok?
