  • Taste buds and taste pores have fully developed by this week, allowing your baby to experience the flavours of the amniotic fluid. 
  • Muscles and bones continue to grow, completing the formation of the skeleton. 
  • The head is becoming more erect and aligning with the body.
  • Delicate hair is starting to emerge on the eyebrows, upper lip, and chin, adding to your baby’s unique features.
  • Between 16 and 18 weeks, the first eye movements become visible beneath the eyelids.

  • Although the ability to hear is still developing, your baby may begin to perceive limited sounds during this week.

16 Weeks Pregnant Bump

As you reach the 16-week mark of your pregnancy, you may find that your baby bump is now unmistakably indicative of the growing life within you. During the second trimester, it’s beneficial to understand that your uterus begins to shift higher and move forward as your baby and womb grow, eventually outgrowing the space within your pelvis. 

It’s important to note that every baby bump at 16 weeks is unique and completely normal. Surprisingly, some women may still not show much at this stage, while others may proudly display more pronounced bumps. As your bump expands, it might be worth considering indulging in some maternity clothes to enhance your comfort and well-being.

16 Weeks Pregnant Symptoms

  • Skin Changes

Increased blood volume and hormonal shifts can give your skin a radiant appearance. Manage breakouts by washing your face twice daily with a mild cleanser.

  • Nosebleeds

Common during the 16th week, nosebleeds can be minimized by humidifying indoor air, moisturizing nostril edges, and clearing each nostril gently.

  • Lower Back Pain

Alleviate discomfort by taking warm baths, stretching regularly, maintaining proper posture, and wearing low-heeled shoes. Exercise and refer to a pregnancy exercise guide.

  • Dizziness

Hormonal changes affecting circulation can cause lightheadedness. Stay hydrated, avoid prolonged standing, and lie down on your side if dizzy. Seek guidance during exercise.

  • Bleeding Gums

Hormonal changes raise blood flow to the gums. Alleviate this symptom by maintaining good oral hygiene and using a soft-bristled toothbrush.

  • Gas

Hormonal fluctuations and a growing uterus contribute to increased gas. Manage it by eating smaller, frequent meals, avoiding gas-inducing foods, and practising gentle exercise.

  • Baby Flutters

Experience the sensation of baby flutters, known as quickening, as early as 16 weeks. First-time pregnancies may notice movements around weeks 18 to 20.

  • Food Cravings

After the first trimester, you may have food cravings due to hormones and nutrient needs. Cravings are common during pregnancy.
