Prenatal blood work for gender

Marguerite • I`m 31 years old married to my wonderful husband Thomas. I have three sweet pups that are my everything and we just brought into the world our little rainbow baby July 7th 2018. After two loses he is our miracle.

Anyone ever have the prenatal blood work that predicts gender and it come out wrong? I had it done and it says we are having a boy. I’m excited and we told people and after we told people I started wondering if it was possibly wrong?
