Missya, WHAT are they talking about? What Rachel said is exactly right. It's based on the age of the egg when it was fertilised, not based on how old you'll be when you're full term. Your baby either has it or doesn't, it doesn't morph over time to create more chromosomes than necessary, just because of your age.

If your risk is now 1:400 and there are no chromosomal abnormalities detected, you are not going to have a Downs baby. That is not to say that there couldn't be something else wrong that cannot be detected by any of these tests - like autism or a generally cranky child 2 years from birth.

It sounds like they're just confusing you and giving you some twisted information. That's my opinion though, don't forget. I'm a bit peeved with the medical profession giving twisted, confusing and worrying information to people who don't understand what they're talking about.

Is there any way you can get some absolute "real person" clarification and not medical gobbldy gook?

Rachel, if you're with a reputable Dr and feel confident in their abilities, you won't regret having the amnio. I certainly don't.
