sequential screening

Mi Bella vida
Anyone done sequential screening? What were your results and was your baby healthy at birth or on the anatomy scan? I was told I'm high risk for my daughter to have trisomy 18. Not sure of the numbers yet, I see genetics next Tuesday. I don't have family history of genetic anomalies, same with my boyfriend. I'm just curious on personal experience. For extra info I'm 25yo Caucasian healthy. Thank you. I'll update with my numbers next Tuesday and again with my level 2 sonogram. I will not be getting CVS or amniocentesis due to the risks being high and my decision not to abort if anything comes up positive.
