I have only ever opted for the one ultrasound - the 19 week morphology scan. For me, I never saw the point in having an earlier scan, and I chose not to take up the option of the NT scan either. You don't get enough info from it, only a probability, and the only way to know for sure whether your baby has Downs Syndrome is to have amnio or CVS which I would not agree to anyway. So it was essentially pointless for me. So basically the reason I only had one scan is because it seemed unnecessary for me to have any more. If I was told that there is a good reason for another one - like suspected placenta praevia, or suspected breech presentation - then I would agree to it. But I am not a big believer in having ultrasounds just to see the baby, or to simply find out the sex. I have bonded just fine with all my babies in the womb without needing to see them.
