Tweety, fwiw I think you have made the right decision, it is debatable what the line is for 'high risk', most people tend to think 1 in 300 is appropriate.

We came back with a high risk nt for ds, which really taught me a lesson! I am very anti nt scans for people who are not at risk because at best it is an inaccurate screening. I however got impatient and decided to have one as I really wanted some pics, couldn't wait to see my bub and had the cash to pay for it (very poor reasons i hindsight). Then, to be told we are high risk and should have an amnio was like a kick in the guts...

I did not agree to an amnio, so opted instead to speak with a genetic counsellor who organized our 20 week scan to be slightly early and with the maternal fetal unit at the nearest large hospital. Along with doing the normal morphology scan they looked for any indicators of abnormality typical to downs syndrome.

I won't say it was easy doing this, it was a very emotional 7 weeks between scans and I spent a lot of time questioning my decision and wondering why I didn't just have an amnio. At the end of the day though, you need to decide what you are comfortable with. I wouldnt have agreed to an amnio unless our result was more than 1 in 30. Something i wasnt prepared for, but this may be different for you as you have an ob, but because i refused an amnio i was not allowed to see team midwives like I had elected and was stuck in the drs clinic until our scan was done and the genetic counsellor had given us a low risk status. I was really not happy about this! Good luck with your next scan, i will be thinking of you.
