In these instances, it may be necessary to have a second ultrasound performed. Starting at the 9th week of pregnancy, your doctor can order a blood test for noninvasive prenatal testing NIPT. During this test, the doctor looks at the placental DNA in your blood to indicate whether there is an increased risk of your child having a genetic disorder.
More testing will be required if your NIPT comes up with positive results. If absent, your baby will be a girl. In this test, amniotic fluid is extracted to check for fetal abnormalities such as cystic fibrosis or spina bifida. Chorionic villus sampling CVS is an invasive prenatal test in which your doctor pulls a sample of chorionic villi from the placenta and examines them for chromosomal disorders, such as sickle cell anemia or Tay-Sachs disease.
Doctors can perform CVS as early as week ten of your pregnancy. Like amniocentesis, CVS is only done if your prenatal screenings come back positive. Therefore, it should not be done for gender determination alone.

Most doctors schedule an ultrasound at around 18 to 21 weeks, but the sex may be determined by ultrasound as early as 14 weeks. Your baby might be in an awkward position, which makes it difficult to clearly see the genitals. But mistakes do happen. Some of these tests according to claims can determine the sex as early as 8 weeks, with about 99 percent accuracy.
This is how it works: You take a sample of your blood, and then send this sample to a lab. The lab checks your blood sample for fetal DNA, looking specifically for the male chromosome. Keep in mind that when sending samples through the mail to an unknown lab there are many factors that may reduce the reliability of the results.
These tests tend to be expensive so you may want to consider whether they are worth the cost for you. A new study finds that epidurals do not affect child development in their later years. A fetal arrhythmia is an irregular heart rate — too fast, too slow, or otherwise outside the norm.
