The best time to do this test is the 11th or 14th week of the first trimester. Because during this time the development of the baby is clearly visible and the placenta is also clearly identified. Doctors do not recommend doing this test before the 11th week of pregnancy. Because it can cause defects in some organs of the fetus.
