27 Weeks Pregnant: Week-by-Week Guide

Congratulations! You’re 27 weeks pregnant. At this stage of your journey, new developments are beginning to unfold. Check out this week-by-week guide to find out what’s in store for your baby and your body in week 27 of pregnancy.

With week 26 of your pregnancy complete, you’re on week 27. Enjoy it, as week 28 is on the horizon!

One of the most exciting things about pregnancy is how many changes you’ll experience with your little one over the span of just 7 days! Here’s some tips and tricks to keep on top of all that’s happening.

At 27 weeks pregnant:

  • Your baby is the size of a cabbage.
  • You’re nearing the end of the second trimester.
  • The countdown continues: you’ve got 13 weeks to go!

What happens during the 27th week of pregnancy?

  • Growth spurt alert! Starting this week, any measure of your baby is now taken from head to toe, which is why your baby has stretched to around 15 inches!
  • Getting a taste for what you like: What you eat can now be tasted by your baby as the nutrients pass into the amniotic fluid. Expose your little one to a variety of flavors through your diet and a range of healthy recipes.
  • Listen up: Even though your baby’s hearing is still muffled by a coat of vernix (wax) over the ears, they may have matured enough to allow the recognition of familiar voices.
  • Almost there: Your little one’s lungs, liver and immune system are continuing to develop. Even though they are not functioning 100%, if they were to be born this week, their chances of survival would be very good.

What should I be feeling at 27 weeks pregnant?

  • You’ve made it to the end of the second trimester, bringing you closer to when you’ll meet your little one face to face. Talk to your healthcare team about where and when you can attend classes for advice on birthing options and newborn care.
  • As your baby grows, you are building a connection—in what you say, what you eat and the little reactions you feel. Studies have shown that bonding with your baby during pregnancy can motivate you to make healthy choices and even ease you into the role of parenthood.
  • You may be feeling emotionally exhausted and stressed as the third trimester mark approaches. Take some time for you to sit with those feelings. Journaling or sharing with a supportive friend helps. Try to remember that feelings of anxiety are common and indicate that you care—studies show that more than 15% of women experience anxiety, but it’s estimated that those numbers are underreported.  
  • Physically, you may experience more aches and pains, especially in your back and feet. Increased instances of heartburn and swelling are common as well.

Week 27 pregnancy symptoms

During week 27 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.

5 common week 27 pregnancy symptoms

  • Peeing when you sneeze does happen, so don’t be embarrassed. If you’re concerned, wear a pantyliner.
  • Your pregnancy hormones will be doing some wonderful things (to offset the nastier symptoms they bring)–including your hair and nails growing faster.
  • Constipation can be reduced with plenty of water and fibrous foods (like beans and veggies in a lentil-spinach soup.) If you’re concerned, ask your doctor about a stool softener.
  • Edema and swelling will mean your ankles and feet are getting less circulation. You may even need to get a larger pair of shoes.
  • Bleeding gums, itchy tummy, blocked nose—it’s all happening in the week 27 potential symptoms department. For the tummy, moisturize frequently (it’ll also help prevent and fade stretch marks.) For the blocked nose, speak to your doctor for advice on the right nasal spray, neti pot or saline solution. With bleeding gums, if they’re bad and you haven’t been to the dentist recently, be sure to book a checkup.

3 expert week 27 tips for a healthy and safe pregnancy

Being 27 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. Now that they can hear you, try singing to your baby or tell them nursery rhymes to bond.
  2. It’s not just your ankles that can swell or become puffy, it’s also your eyes. A cold compress can help alleviate discomfort.
