What to Expect:

What to expect at 16 weeks pregnant? During this week, your uterus is about halfway between your pubic bone and your navel. The round ligaments that support it are stretching to accommodate your growing fetus — and soon, your tummy will get really big!

  • Less nausea, fewer mood swings, and more energy will probably give a feeling of overall well-being as well. Your sex drive may be up as well, and unless your doctor has advised you otherwise, you can always get intimate with your partner!
  • But the most exciting part is feeling your baby’s movements! Many women experience this around week 16, but others don’t feel any quickening until week 18. If you can’t feel your baby moving right now, don’t worry — soon, you will. Since the earliest movements often feel like popcorn popping, gas bubbles, or fluttering, you may not even realize it was your baby moving! Over the next weeks, the movements will get stronger and you’ll feel them more frequently.
  • When you're 16 weeks pregnant it usually comes with bloating, constipation, gas, and indigestion, which are very common during this phase in your pregnancy. And guess who’s to blame for them? You’ve guessed it — your hormones! Scroll down to the “Tips” section to learn more about how you can relieve these symptoms and improve digestion.

Your Baby at 16 Weeks

It’s incredible just how much a baby can grow from week to week! Right now, he’s about the size of an avocado, measuring around 11.5cm (or 4 1/2 inches) head to rump. All his limbs and joints are now fully formed, and his body’s proportions are more size wise as well. His head is more erect and straightened out thanks to his neck elongating, and his scalp pattern has started to form already. Week 16 marks a big growth spur — and get ready for more!

16 weeks pregnant

His tiny heart is pumping about 25 quarts of blood now, and this amount will increase as your pregnancy progresses. His nervous system has begun to make connections with the muscles, so your baby will soon develop reflexes and start moving more purposefully. Facial expressions are beginning to appear too. The skin is still translucent at this point, with the blood vessels clearly visible under the skin. The baby’s eyes have also moved closer to the center of his face. It won’t be long until you’ll give birth to this beautifully tiny human, and he still has to go through numerous growth phases before that happens!

Pregnancy Tips

  • Enrich your diet with fiber-rich vegetables and fruits like apples and pears to aid in digestion and help with constipation, bloating, and gas. Also, junk food should be avoided as much as possible, especially when food cravings kick in as you’re particularly susceptible to eating a lot of them. Don’t forget that you should add another 300 calories to your recommended daily calorie intake, but each of them should count — so no French fries, burgers, or chocolate cakes!
  • Drink water or unsweetened herbal tea instead of juice.
  • If you haven’t already, consider taking some prenatal workout classes to exercise regularly and stay fit. Weight issues can interfere with birth, so you’ll want to get as much exercise as possible during this phase of pregnancy.
  • Schedule an appointment for amniocentesis if you haven’t already to detect potential chromosomal and genetic disorders early on, and make sure to encourage communication with your partner so your relationship stays healthy and strong!
