This soft colorless hair is called lanugo, and it will eventually cover most of your baby's body until it's shed just before delivery.</p> <p><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/babyslideshow.html/" style="line-height: 16.8px;"><img class="right" title="Watch Your Baby Grow" src="https://kidshealth.org/EN/images/promos/PregCal-BabyGrow-enPR.jpg" alt="Watch Your Baby Grow" /></a>By now, your baby's genitals have fully developed, though they may still be difficult to detect on an ultrasound. Your baby also starts to produce thyroid hormones because the thyroid gland has matured.</p> <p>Your baby now weighs about 1.6 ounces (45 grams) and is about 3.5 inches (9 cm) long from crown to rump.</p> <p><img class="left" style="line-height: 16.8px;" title="Week 14" src="https://kidshealth.org/EN/images/galleries/PregCal-Week14-enGL.jpg" alt="Week 14" /></p> <h3>Your Body</h3> <p><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/momandbaby-slideshow.html/"><img class="right" title="" src="https://kidshealth.org/EN/images/buttons/PregnancySlideshow-Belly-enBT-1.png" alt="Watch your belly grow!" /></a>Your health care provider may discuss&nbsp;<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/prenatal-tests.html/">amniocentesis</a>&nbsp;with you if&nbsp;you're older than 35 or if your screening tests indicated that there may be a problem with the fetus. Amniocentesis is a test usually done between 15 and 18 weeks that can detect abnormalities in a fetus, such as <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/down-syndrome.html/">Down syndrome</a>.</p> <p>During this test, a very thin needle is inserted into the amniotic fluid surrounding the baby to take a sample of the fluid for analysis. Amniocentesis does carry a very slight risk of miscarriage, so talk to your health care provider about your concerns and the risks and advantages of the test.</p> <p> <script
