I am 40 years old and 18 weeks pregnant.All of my 1st trimester genetic screenings were normal(triple screen and NTS) showing I was at low risk for defects..My 2nd trimester screening came back abnormal bringing the numbers from 1 in 319 down to 1 in 43 for Down's.I have another ultrasound scheduled in 2 weeks at the perinatal center..what would cause the change in the reading from being normal 6 weeks ago to abnormal now?
