scared out of my dang mind

Caroline
Hello October mommies!!!!
I just wanted to know has anyone experienced a 12 week scan that shows fluid around the baby's heart and also the placenta covering the uterus (partial)?
My doctor stated that I would have to complete the Harmony test to check for Down syndrome and now I have to see a high risk doctor for further evaluation! I am so scared out of my mind and I'm not sure if anyone had this or is going through this as well
