Ultrasound is one of the screening tests that may be done in the first trimester to look for birth defects, such as Down syndrome. The first-trimester screening test uses ultrasound to measure the thickness of the skin at the back of the baby's neck.
An ultrasound is perhaps the most common way to detect the sex of your baby. With an ultrasound, you can probably not detect the sex of yore baby until sometime between week 16 and week 20 of pregnancy. Having said that, there are a great many factors that go into how early you can detect the sex of your baby using an ultrasound. Everything from gestational age to the thickness of the motherâs abdominal wall can affect the amount of time that this process will take. An ultrasound is, after the 20th week of pregnancy, generally more than 90% accurate at being able to tell a babyâs sex.
