I'm sorry you're going through this stress. Unfortunately, screening scans are not 100% accurate, which is why diagnostic tests like amnio are recommended, if you want a definate diagnosis. By definition, the NT scan is just to screen for risk. The risk is based on averages, which may or may not apply to your child. Early scans do not pick up everything. Both my boys were perfectly healthy according to their 12 week scan, yet they both had fatal conditions. Some DS children are not 'detected' through scans at all and it is only discovered after birth.

You should have been referred to a genetic counsellor to talk this through. Has that been done? They can talk you through the risks involved in an amnio vs waiting longer to find out. Whilst many people will tell you to keep positive, which is great, I understand that is hard to do when faced with the possibility your child can be extremely sick.

Other people will have their own opinion about what decision they think you should or shouldn't make. It's actually none of their business. We make the best and most loving decision based on what is best for our child and our family. Whilst it's true that some people with Down Syndrome can live relatively 'normal' lives, it's also true that most of them do not and are faced with a number of serious, lifelong health issues. That is what a genetic counsellor should be talking through with you. You can also contact a Down Sydrome association or support organisation to discuss.

As for the amnio itself, ask that an experienced doctor does it, preferably a Maternal Fetal Medicine specialist. That will reduce the risk of miscarriage. Do you have someone to support you through this? It's a very scary, stressful time so I hope you have someone to talk to.
