What’s happening with the baby at 16 weeks pregnant?

Baby’s face and features

Your baby’s face is continuing to develop. The eyelids are almost fully formed, and they may be able to blink, although their eyes are still closed. The lips, nostrils, and eyebrows are becoming more defined, and tiny teeth buds are forming beneath the gums.

Skeletal development

Your baby’s bones are becoming stronger, and the skeleton is developing and hardening. They are still covered in soft cartilage, but it will continue to harden into bone over the next few weeks.

Movement

Although you may not feel it just yet, your baby is starting to move around more. At 16 weeks, they have developed more muscle strength, and their movements are becoming more coordinated. Your baby may be stretching, kicking, or even turning and twisting — though most women don’t feel these movements until later in the pregnancy.

Baby’s skin

At this stage, your baby’s skin is still thin and translucent. It will continue to thicken over the coming weeks, but it remains very delicate. The first layers of fat are beginning to form under the skin, helping to smooth out the appearance of their body.

Development of senses

Your baby’s sense of hearing is developing, and by 16 weeks, they may be able to hear sounds from outside the womb, like your voice or other noises. The hair follicles are forming on your baby’s head, though they won’t have a full head of hair yet.

Heartbeat and circulatory system

The heart is beating strongly at around 150-160 beats per minute, and the circulatory system is becoming more developed. The heart is pumping about 25 quarts of blood a day. The kidneys are also functioning, and your baby is starting to make urine.

Baby’s growth continues

Your baby is growing at an incredible rate, and their organs and body systems are maturing. They are starting to look more like a little person and less like a tiny embryo. The next few weeks will bring even more rapid development as they approach the halfway point of the pregnancy.

How big is your baby at 16 weeks pregnant?

At 16 weeks, your baby is about the size of an avocado. They measure around 11.5 centimeters long and weigh about 100 grams. Your baby’s body is becoming more proportional, with the legs growing longer than the arms.

How is your belly at 16 weeks pregnant?

Your uterus is now about the size of a grapefruit and is moving above your pelvic bone. As a result, you may start to see a small but round bump, especially if it’s your second pregnancy or later. For first-time moms, it might still be a bit subtle.

You may notice that your belly has a firmer texture, and it may feel a little bloated or tight. The abdominal muscles are stretching to accommodate your growing uterus, which might cause some discomfort.

Common symptoms and how to manage them?

1. Increased energy and better mood

Many women experience a boost in energy during the second trimester, and you might notice that you’re feeling less fatigued than before. Your mood may also stabilize, and the emotional rollercoaster of the first trimester might start to even out.

How to manage:

• Enjoy your newfound energy! This is a great time to catch up on tasks or enjoy activities that you may have felt too tired for earlier.

• Continue practicing self-care and finding a good balance between staying active and getting enough rest.

2. Growing belly and round ligament pain

As your uterus grows, you may experience round ligament pain, which is caused by the stretching of the ligaments that support your uterus. This can feel like sharp or dull pain on one or both sides of your abdomen, often when you change positions quickly.

How to manage:

• Avoid sudden movements that might trigger pain.

• Wear supportive clothing like maternity belts if needed to help alleviate the pressure.

• Stretch gently and rest if you feel any discomfort.

3. Stretch marks and skin changes

As your belly grows, you might notice stretch marks beginning to appear. Your skin may also start showing other changes, such as the "linea nigra" (a dark line running down your abdomen) or darkening of the skin around your nipples.

How to manage:

• Use moisturizing lotions or oils to help keep your skin hydrated and possibly minimize the appearance of stretch marks.

• Wear sunscreen to protect your skin from hyperpigmentation, especially as hormones can make your skin more sensitive to the sun.

4. Congestion or nosebleeds

Hormonal changes can cause increased blood flow to the mucous membranes, leading to nasal congestion, dryness, or even nosebleeds. This is a common symptom during pregnancy.

How to manage:

• Use a humidifier in your room to keep the air moist.

• Stay hydrated and use saline nasal sprays to relieve congestion.

• Avoid overly dry environments or allergens that can worsen the symptoms.

5. Heartburn and indigestion

As your pregnancy progresses, your growing uterus may begin to push up against your stomach, causing heartburn or acid reflux. You might also experience bloating and gas.

How to manage:

• Eat smaller, more frequent meals instead of large meals.

• Avoid spicy, greasy, or acidic foods that can trigger heartburn.

• Sleep with your head elevated and try not to lie down immediately after eating.

6. Increased vaginal discharge

It’s normal to notice more vaginal discharge at this point in pregnancy. This is your body’s way of preventing infections by keeping the vagina clean.

How to manage:

• Wear breathable cotton underwear and change your panty liners regularly.

• If you notice any unusual color, odor, or itching, contact your doctor to rule out any infection.

7. Mild swelling in feet and ankles

Although more common later in pregnancy, mild swelling in your feet or ankles can start at 16 weeks as your body retains more fluids.

How to manage:

• Elevate your feet when you can.

• Avoid standing or sitting for long periods.

• Drink plenty of water to help flush out excess fluid.

Frequently asked questions at 16 weeks pregnant

When will I feel my baby move?

At 16 weeks, your baby is already moving around, but it may be too early for you to feel it. Most women start to feel the first movements between 16 and 25 weeks, often described as "quickening." If this is your first pregnancy, you might not feel it until a little later. Moms who’ve been pregnant before often feel movements earlier.

Is it safe to have sex at 16 weeks pregnant?

Yes, in most cases, sex is safe during pregnancy as long as there are no complications. By 16 weeks, you may feel more comfortable as the risk of miscarriage drops. Many women experience an increased sex drive due to hormonal changes, though comfort levels can vary. Always check with your healthcare provider if you have any concerns or complications.

Are there any tests or screenings at 16 weeks?

At 16 weeks, you may be offered genetic screening tests, such as the quadruple screen or amniocentesis (if you're at risk for genetic disorders). These tests check for markers of potential birth defects or genetic conditions. It’s a good time to discuss any testing options with your doctor if you haven’t already.

Is it normal to have changes in my skin at 16 weeks?

Yes, skin changes are common during pregnancy due to hormonal fluctuations. Some women notice a pregnancy glow, while others may experience darkening of the skin around the nipples, face (melasma), or along the abdomen (linea nigra). Stretch marks may also start to appear as your belly grows. Using moisturizers can help keep the skin hydrated.

Can I travel during pregnancy at 16 weeks?

In most cases, traveling during pregnancy is safe, especially during the second trimester when the risk of complications is lower. However, it’s important to stay hydrated, take breaks to stretch and walk, and avoid strenuous activities. If you’re planning to travel long distances, check with your healthcare provider to ensure it’s safe for you and your baby.

What should I be eating at 16 weeks pregnant?

At 16 weeks, it’s important to maintain a balanced diet rich in folic acid, protein, calcium, and iron to support your baby’s growth. Include foods like leafy greens, lean meats, eggs, dairy, whole grains, and fruits. Make sure to drink plenty of water to stay hydrated and support increased blood flow.
