Prenatal screening

Just curious - I had the Prequel Prenatal Screening done from Myriad, used to be Counsyl, and I was curious about it for gender. We found out what we are having and just wanted to hear if anyone else had it and the accuracy of it. My fetal fraction was also 11.3% which from what I have been reading is insanely high for a sample so not sure what that really means.
