Baby Development
Your baby's head is now upright, and the eyes can move slowly. The ears are also close to reaching their final position. The skin is getting thicker, and limb movements are becoming more coordinated. While you likely won't feel these movements yet, they can be seen during an ultrasound exam. Your baby is now about 4.75 inches (120 millimeters) long from crown to rump and weighs about 4 ounces (110 grams).
Your Body This Week
You may start to feel the first flutters of your baby's movements, known as quickening. This can feel like a gentle bubbling or a light tapping. Don't worry if you don't feel it yet, as it can vary from person to person. Your healthcare provider will also be monitoring your weight gain and blood pressure at your prenatal appointments.

At 16 weeks of pregnancy, you're in the second trimester, a time marked by continued and comforting developments as your body adjusts to nurture your growing baby. Though the first-trimester nausea and fatigue may begin to wane, allowing you more energy, you might still notice breast tenderness and sensitivity as the mammary glands continue preparing for lactation. Hormonal changes, especially the rise of estrogen and progesterone, continue to play a significant role in your body’s adaptations, ensuring energy is stored and used efficiently to support fetal growth. It's crucial to maintain a balanced diet rich in nutrients rather than focusing on caloric increase; prioritize whole foods like fruits, vegetables, lean proteins, and whole grains. Staying hydrated and incorporating small, frequent meals can also help stabilize energy levels and manage any lingering morning sickness. Engage in moderate exercise, such as brisk walking or prenatal yoga, to enhance your mood and physical well-being. Trust your body; each pregnancy is unique, and symptoms such as the absence of morning sickness don't necessarily indicate issues, especially with confirmed healthy progress in earlier weeks. As always, regular check-ups and communication with your healthcare provider are vital to ensuring both you and your baby are thriving.
