Anatomy scan found 2 markers?!?!

Amanda • Married and have our beautiful daughter 👨‍👩‍👧
So we went for our anatomy scan today and found out we're having a girl!!! So exciting but then the doc came in and said they spotted 2 "soft markers" includingn a cyst or sac of fluid on he brain and Echogenic intraventricular focus which is a calcification on the heart.  All my other tests came back low risk so the doc wasn't too concerned but she said now instead of 1 in 5000 risk I have a 1 in 2500 risk of baby having Down's syndrome.  We are getting the blood test for genetic screening done today but I am freaking out has anyone had this before??
