Inaccurate NIPT test for Sex

Heather

I took the Innatal (Progenity) test at 11 weeks & it said Boy. I am 19 weeks now & just did anatomy scan- my high risk doctor said 100% healthy baby Girl!!

Has anyone had a false sex result from an NIPT test? My doctor also thinks I had a vanishing twin (they found an empty sack at 6 weeks- no fetal pole). This is my second pregnancy, I have one boy.

I’m a little nervous this could be a bigger issue, they are redoing the NIPT test- but wanted to hear if other people have experienced this?
