Thick Nuchal Fold 19.5 week U/S

Ka

Okay, so on my anatomy scan, they found out my baby has a thick neck/nuchal fold. Normal is 6mm and under. My baby’s measured an average between 6.5-7.5mm. They called me and told me that this could be indicative of genetic problems like Down Syndrome. There were no other markers. I’m seriously panicking. Has anybody else had this happen? I’m getting a Panorama test tomorrow (I tried earlier in my pregnancy, but there was not enough fetal DNA to test) and I have an appointment with a specialist. I have a healthy daughter, 3 miscarriages, and now this. I wish I could have a healthy, stress free pregnancy😭😭😭
