does anyone have any experience of this?
My sister has just had a nuchal fold scan at 12 weeks and was told that the umbilical cord only has one artery and one vein. supposed to have two arteries apparently, although i'm also pregnant and it has never been mentioned to me.
she was told not to worry although of course she's looked it up and found lots of awful statistics about abnormalities and is now understandably worried sick.
can anyone help?
