Patient's question:
Anterior uterus, significantly enlarged in size, with a fetus visible inside, head diameter 17mm: Fetal heart rate and fetal movement observed: Anterior wall placenta, Grade 0: Amniotic fluid dark area 42mm: Partial fetal limbs visible. This is the ultrasound I had on April 2nd. Could you please tell me how many weeks the fetus is now? Is it possible to do the Down syndrome screening?Doctor's answer:
Generally, the Down syndrome screening can be done around weeks 16-20 of pregnancy. Based on your ultrasound gestational sac size, the calculated gestational age is around week 12, and at this time, it is not advisable to rush into the Down syndrome screening. Guidelines: Down syndrome screening should be performed at the optimal time to ensure more accurate results. Ultrasound estimates of gestational age may have some errors, and the gestational age should be calculated from the first day of your last menstrual period. It is highly recommended that this test be performed.
