Week 14

My Baby's Development

By this week, some fine hairs (lanugo) have developed on your baby’s face. It is soft colorless hair, eventually covers most of your baby’s body until it is shed just before delivery.

Your baby’s genitals have fully developed by now. But they may still be difficult to detect on an ultrasound examination. Once the thyroid gland has matured, your baby starts to produce thyroid hormones. Your baby is about 3.5 inches (9cm) long from crown to rump and weighs about 1.6 ounces (45g).

My Body

Under few circumstances (for example, if you're older than 35), your health care provider may request a test of amniocentesis. Amniocentesis is a test that usually done in week 15 to 18. It can detect abnormalities in a fetus (such as Down syndrome). During the test, a very thin needle is inserted into the amniotic fluid surrounding the baby in the uterus. A sample of the fluid will be taken and analyzed. Amniocentesis does carry a very slight risk of miscarriage. So, consult your health care provider about your concerns, the risks and advantages of the test.
