Does anyone know how many weeks pregnant you must be before having a nuchal fold scan at Salisbury hospital? We had one with dd1 and am now 6 weeks pg with no.2. We had disappointing results first time round with a combined nuchal fold scan and blood test and opted for an amnio to find out for sure. Although everything was ok, it was a very traumatic time for all the family so we'd like to know the odds before we tell anyone that I'm expecting to avoid the daily deliberations
