Hi guys, on Monday I had my combined results which produced risk of ds as 1/21. I’m absolutely terrified! This is an Ivf pregnancy , had vanishing twin. Iona test done Tuesday but unsure about accuracy due to the vanishing twin aspect! Nt was 2.6mm at 13 weeks , Papp-a o.6, hcg2.2. I’m 38, any experiences or common ground would be much appreciated thank
