The Mom:


Usually around 16 weeks, you will have a couple of prenatal testing options made available to you. Once of the most common is the ultrasound. This technology uses sound waves to see your baby. It's painless, although you may be asked to have a full bladder, which can be a bit uncomfortable.

You will lie on a table, and your stomach will be lubricated to help the scanner move across it. Ultrasounds can be used to determin fetal age, many abnormalities of the head and spine, the delveloment of the major organs, such as heart, kidneys, and stomach. It can also determine twins, the placement of the placenta and sometimes, the baby's sex. If you don't want to know, be sure to tell your ultrasound technichian beforehand. Remember, it's not a guarantee, so, you may not want to paint the nursery based on it.

Alphafetoprotein testing (AFP) is another option. This test measures the amount of AFP present in your blood. It is usually done between 16 - 18 weeks. It can detect such problems as spina bifida, anencephaly and possibly Down's Syndrome. If the test comes back as abnormal, you can have it confirmed with another AFP test or it's possible your provide may recommend you have amniocentesis. Risks of AFP are small. If you have concerns, discuss them with your provider.

Amniocentesis, a test done with a sample of your amniotic fluid withdrawal by syringe, may also be recommended if you are over 35. Women over 35 are thought to have higher risks associated with many chromosomal problems. There are more risks to amnio than other prenatal testing. Some of these include: trauma to the baby, placenta or umbilical cord; infection, or premature labor. Your provider should cover all these when you if an amnio is recommended.

It may be as late as your 20th week before you feel those first little flutters. The lanugo hair is present, and covers your baby's head and body.
