Hey hun, my DD had a cystic hygroma. It was diagnosed through ultrasound. We had the 12 week scan and went through eight weeks of hell before we were cleared. After ruling out all chromosomal and organ abnormalities, they decided it was most likely a cystic hygroma causing the thickened fold.

We were told that it would either resolve itself in utero or that she may need a small surgical procedure at birth. It resolved in utero and she was born healthy and perfect and is now a whirlwind of a preschooler.

Hoping for the same result for you xx

ETA - our risk for DS was 1:6 we had a one in ten chance that DD would be born at term, healthy and alive. 9 in ten that she wouldn't. We faced horrible odds... And she is fine
