Answer: An ultrasound is the least invasive way to find out if you are having a boy or a girl. It is best done during the 18-22nd weeks of your pregnancy.
Tests. 1  Get an ultra-sound. 2  Undergoing amniocentesis, which is sometimes done on pregnant women who are 35 years old or older, can reveal the gender. 3  Have the CVS or chorionic villus sampling test done, which is performed during the first trimester of pregnancy and can determine if there are problems with the baby's chromosomes. This test will reveal the baby's gender. Keep in mind that CVS or amniocentesis are not generally done simply to determine a baby's sex.
