Anyone opt out of Down syndrome and glucose test?

I didn't take those tests as i was financially tight. Baby is fine. I also dont want additional stres if there's something wrong with the tests. Blood test were only done up to 2nd trimester. Other than that, they had vaginal swab(check for any infections), GD (test for diabetes). Also, vaccines ( flu and whooping cough) . I don't remember taking any blood test other than GD in the last trimester
