White spot on heart at anatomy scan

li

I'm 19+4. Baby measured perfect and weighs 13oz. But the anatomy scan revealed he has 2 white spots on his heart and that's a soft marker for down syndrome. He wouldn't cooperate to get the rest of the pictures but my doctor is referring me to a high risk OB for a more in depth ultrasound and genetic testing (I didn't do any tests at 12 or 16 weeks because it doesn't change anything for us). I'm basically just in limbo waiting for more answers but if this is what's meant to happen, we are ready.

Just look at our baby boy, I am so excited to meet him!
