Hi, as you’re officially in 2nd trimester you cannot do the OSCAR test for Down syndrome. But you can still do NIPT which is more accurate (and more expensive) than OSCAR. NIPT tests for abnormalities in fetus using your blood sample. Can also learn the baby gender thru it. Your gynae will also be able to perform the other standard tests like detailed ultrasound, basic blood and urine test and give you any supplements to take.
