Genetic testing odds

Hey all! I had blood draws in my first and second trimesters, and an anatomy scan. Everything on these tests gave me a less than 1% chance for having a baby with abnormalities. Highest odd was 1/910, for the Down’s syndrome test. I did not have the NT scan. Has anyone personally had odds like this, and went on to give birth to a baby who had Down’s? Zero soft markers were found at the anatomy scan, nasal bone was pictured, but not measured. Legs measuring very long.
