With DD (who is now 4) I was given a 1 in 30 chance that she had Downs Syndrome following my blood tests.
I wasn't asked whether I wanted an amnio. The midwife phoned me at 9pm with the results, and told me to come in to "chat" with the consultant the next morning.
When I got there the consultant was obviously under the impression that this "chat" involved performing the amnio as he had everything set up!
I firmly told him that I did not want an amnio due to the risks that came with it. I knew that if the results did say that she had DS I wouldn't terminate, so the risks seemed silly to take.
I was basically told that I was being irresponsible, and that I should think about my 2 other children and how they would cope. However, having worked for a number of years with children with disabilities I knew that we'd cope!
From that moment on I didn't get a scrap of support from the consultant. However one midwife was brilliant, totally supported my decision, and when DD was born she arranged for a paediatrician to see her straight away to see if she appeared to have DS.
She didn't have DS, which made me even more sure that I made the right decision. But even if she had she would still have been my little girl and I would never have terminated.
With hindsight I shouldn't have even had the bloodtests, and if I ever have a 4th I don't think I will bother as they just caused moths of unnecessary worry.
I wouldn't judge anyone else's decision, but just thought it might be helpful to share my experience.
