XP: Echogenic Bowel at u/s ??

togo

I had another Anatomy Scan on Friday and they said that both babies have an echogenic bowel. I am so nervous that they have down's syndrome. The dr. didn't seem too concerned with it, but she did mention talking to my OB about an amnio. I'm 30 and the only other soft marker is that one baby has two vessel umblilical cord. They are identical and that makes me think that they may have something serious since they both have the echogenic bowel.

Has anyone seen this at their scan and things turned out ok? Did it go away on it's own? I'm strongly considering having an Amnio done. I'm so so nervous.
