If you want to be sure without risking miscarriage via a cvs/amnio, you can get the blood test instead. I think there are 2 commercial brands available - MaterniT21 Plus and Harmony. They have a 99% accuracy for detection of trisomies 21, 18 & 13. It's extremely expensive - about $1500 - 2000. However, it's a good option instead of amnio for those conditions.
I also agree with talking to a genetic counsellor. You should be able to get a referral through your GP or OB.
ETA - apparently there is also another brand called verifi and it is $1250.
