Hoping someone may have some advice...... I'm booked in for harmony testing when I'll be exactly 10 weeks pregnant. I know the hospital will scan me too and hoping that if the nuchal fold measurement is within range then this will be a good sign and make the wait for results a little easier (previous pregnancy with high nuchal fold picked up at 12 week scan. Chromosome disorder confirmed shortly afterwards). I know nhs hospitals will only check this measurement at 12 week scan after 11+2 (?) but not sure how much it could potentially change in just over a week????
