Have any of you moms ever gone to an ultrasound and had them find EIF? I understand it can be a soft marker for Downs but other than that I haven't found much info on it. I have to go back in for a follow up ultrasound with the perinatalogist but of course it's not for another four weeks. So now I sit and worry. Just wondering if anyone can give me insight or a personal experience and how it turned out? My husband is especially worried and I would like to ease his mind a little....
