I think you have to understand the terminology. There is no "positive," and "negative." There is HIGH risk, or LOW risk. That is not the same as positive. You are at an elevated risk, but that doesn't necessarily mean much. I was around the same risk as you, and I was in my mid twenties when my son was conceived. He is great!! If you feel you need 100%, get the amnio. Now, there are a lot of people who will say "If you are going to keep the baby, why get the amnio?" Well, some people want to be prepared. There are certain things that babies with disabilities need immediately after birth. There are also people who simply want to be prepared for the unique challenges. I would not stress too much. The high risk Dr. I went to, said those tests are so flawed. The great majority that come to him, end up having very normal babies.
