High risk nipt

Marina

Has anyone had a high risk result due to low fetal fraction? My fetal fraction was 2.7 and I guess cause of my age it now puts me at a 1/17 risk for triploidy, trisomy 8 or 13. I’m waiting to have an advanced ultrasound to determine any abnormalities but anyone with any knowledge of this? I’m not overweight by much maybe 15-20 pounds I’m 150-5ft2inches 37 years old. I’m super scared and nervous....
