Your baby at 19 weeks pregnant

What's happening in there

  • Your baby is the size of a mango.
  • You’re already at week 19.
  • The countdown continues: you’ve got 21 weeks to go!

What happens during the 19th week of pregnancy?

  • Baby's hard-wired: Nerve cells, or neurons, are connecting with the muscles. Coupled with hardening bones and lengthening arms and legs, baby is able to move around and kick. 
  • Bubble wrapped: Not quite, but at this stage, your baby’s skin is covered in vernix caseosa, a whitish substance that protects their skin from infection and prevents scratches and abrasions. There’s also a layer of brown fat developing to provide warmth once on the outside.
  • Nice hair: Your little one’s hair and eyebrows are growing. 

What should I be feeling at 19 weeks pregnant?

  • You may experience difficulty sleeping, thanks to everything from your belly bump to leg cramps to increased urination. Try sleeping on your side, cuddling with a pillow, and taking other steps to help you get the rest you need.
  • Your baby may be kicking up a storm. Enjoy those fantastic flutters, which may feel stronger every day.
  • The skin on your expanding belly may be dry, tight, and itchy.
  • You may be experiencing pregnancy brain. Also known as  “mommy brain,” pregnancy brain is a real thing and can leave you feeling foggy and forgetful. Check out these tips that can help reduce these symptoms.

What is the baby’s position at 19 weeks pregnant?

A 19-week fetus has plenty of space to keep busy moving and floating around. Kind of like a toddler, they’re always on the go! But the larger a baby grows, the more limited repositioning movements will become. During the last weeks of your third trimester, baby will start moving into a birth position.

Week 19 pregnancy symptoms

During week 19 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

8 common week 19 pregnancy symptoms

  • Sore back or sciatica can cause you pain at this stage. You’re growing rapidly, and the extra weight and stretched muscles can hurt. Stretching or gentle movements may help. Check with your doctor to see if yoga or Pilates are safe for you. Consider adding a support cushion to your office chair as well.
  • You may get stretch marks as your tummy grows, but there are plenty of preventative stretch mark creams available—you can even make your own!.
  • Your sleep may be getting disturbed. A few basic changes can help.
  • Swelling in your nasal passages can cause a stuffy nose and nose bleeds. Saline nasal sprays and humidifiers can provide some relief.
  • Yeast infections are a strong likelihood during pregnancy, so ask your doctor about preferred treatments.
  • Your baby’s hair is growing and yours may be too. Hair shedding slows down, so your hair may look thicker.
  • Watch for bleeding or swollen gums. Higher progesterone levels during pregnancy can affect your oral health and leave you more susceptible to gingivitis.
  • If your bump wasn’t noticeable already, it is now. But remember, every mom-to-be is different, and first-time moms can show a lot later than mamas who’ve had previous pregnancies.

3 expert tips for a healthy and safe pregnancy

Being 19 weeks pregnant is an important time for you and your baby. Here’s some more expert-recommended advice on how to adjust to this new stage and keep you and your baby safe.

  1. With the mid-pregnancy ultrasound coming up, you have the potential to learn your baby’s sex (or not). Decide if you want to know the gender of your baby before you head to the appointment.
  2. If you haven’t already, now is a good time to find a pediatrician who can serve as your baby’s doctor once they make their way into the world.
  3. Heartburn is one of the most unpleasant and regular symptoms you can experience when you’re pregnant. Learn what to eat to reduce the effects of heartburn.

19 week pregnancy diet

Continue to consume a nourishing, nutritious, well-balanced diet, with a special focus on foods rich in iron and DHA (docosahexaenoic acid), an omega-3 fatty acid that’s important for your baby’s growth and development.
