Any mommies out there have an Echogenic intracardiac foci (EIF) aka a soft marker for downs syndrome come up in their 20+ week ultrasound? My doc said nothing to be worried about and that we'll check back on it before due date. I'll be going to see a perinatologist for further testing soon. I just want a healthy baby with a healthy heart. There's no doubt I'll love him w or w/o ds. My only concern is his health.
