As you mentioned Bel, it's really hard for anyone to give an answer to reassure you, because we can't see what the ultrasound person did, we don't know much about it like yourself, and not many (any?) of us who posted have had this problem. So i think people were just trying to support you in a different way, perhaps trying to reassure you that it may be nothing to worry about due to inaccuracies with testing - they just didn't have any insight with such little info. Ask lots of questions tomorrow and we'll look forward to finding out more

If you want more info on testing and accuracy there is a book by Lachlan De Crespigny called 'Pre-Natal Testing.' See below.

Prenatal Testing by Lachlan De Crespigny
Published by Penguin Books, RRP AUD$22.00

Prenatal diagnosis is a rapidly developing area and, as couples increasingly have children later in life, nearly 20% of pregnant women are offered testing because of their age. There is no uniformity in the way pregnant women are presented with the often difficult decision regarding prenatal testing and, if an abnormality is found, women have few guidelines to help them to decide what to do.

Prenatal Testing presents the stories of women and their partners who have made such decision, supported by information about medical procedures and counselling. It offers vital guidance through a decision-making process that takes place at many levels – before and after testing, and between couples and family members as well as individuals and the medical profession.

Lachlan de Crespigny is a partner at the private clinic, Melbourne Ultrasound for Women, which sees approximately 10,000 patients a year, and head of the Ultrasound Department. A former president of the Australasian Society for Ultrasound Medicine, he is the country’s most prominent spokesperson on prenatal testing. He has published over 60 articles and book chapters in national and international publications, in addition to several bestselling books.
