At week 15 of pregnancy<\/strong>, your baby and your body are going through significant changes. You may begin to feel more energetic, your appetite may increase, and your baby is developing rapidly inside your womb. Here\u2019s everything you need to know about this exciting week.<\/p>\n

\ud83d\udc76 Fetal Development at Week 15 of Pregnancy<\/h2>\n

By week 15<\/strong>, your baby measures about 10 centimeters (4 inches)<\/strong> from head to bottom \u2014 roughly the size of an apple. A thin, soft layer of hair called lanugo<\/strong> now covers the baby\u2019s skin to protect it. Eyebrows and eyelashes begin to form, and the baby\u2019s eyes are becoming sensitive to light<\/strong>, even though they remain closed. These are signs that the nervous and sensory systems<\/strong> are developing quickly.<\/p>\n

Your baby is now practicing movements by squinting, frowning, smiling, and moving the lips<\/strong>, helping strengthen developing muscles. The skin is still thin and almost transparent, allowing tiny blood vessels to show underneath.<\/p>\n

The skeletal system<\/strong> continues to form as soft cartilage slowly turns into bone through calcium absorption<\/strong>. Although the bones are getting stronger, they remain flexible enough to help your baby move through the birth canal<\/strong> later on.<\/p>\n

The ears<\/strong> are nearly in their final position, and the baby can now turn the head<\/strong> and move the thumbs and fingers<\/strong>, though most movements are still involuntary<\/strong>.
Fine hair growth<\/strong> has also started, and light pigmentation may begin to appear.<\/p>\n

If you\u2019re curious about your baby\u2019s gender, week 15 is a good time<\/strong> to find out. The external sex organs are now developed enough that an ultrasound<\/strong> can usually reveal whether you\u2019re expecting a boy or a girl.<\/p>\n

\ud83e\udd30 Your Body and Key Tests at Week 15 of Pregnancy<\/h2>\n

During the second trimester<\/strong>, several prenatal screening tests<\/strong> are performed to assess the baby\u2019s health.
