genetic screening

Tammy
I'm 40 and TTC my 3rd child. When I finally conceive I'm debating whether to pursue genetic testing or not. My doctor already told me because of my age OHIP blood test will probably come back positive bc I'm over the cut off age. I'm leary about doing the Amnio or the other test that takes a sample of the placenta. The whole idea if both scares the he'll out of me. I also don't want to risk a miscarriage. Had anyone else proceeding with either test? I'd love to hear your thoughts.
