I've been reading more about scans and am not sure that I want to have both of the standard 12-week and 20-week ones. If I'm reading it right, the 12-week looks to see how many babies there are, that the placenta is in the right place and that's when they do the nuchal testing. That one seems more important to me. But what is the purpose of the 20-week scan other than to test for abnormalities? If I know I wouldn't abort even if there were something terribly wrong with the baby, is there really any point in having it done? I know most people jump at the chance to have as many scans as possible but I think they are kind of needless and studies have not concluded that they are completely harmless to the fetus.
Has anyone refused a scan? If so, why and how did your care provider react? Which scan(s) did you skip?
