31 Weeks Pregnant: Week-by-Week Guide

31 Weeks Pregnant: Week-by-Week Guide

Congratulations! You’re 31 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 31 of pregnancy.

With week 30 of your pregnancy complete, you’re on week 31. Enjoy it, as week 32 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 31 weeks pregnant:

  • Your baby is the size of a coconut.
  • You're into the seventh month and third trimester.
  • The countdown continues: you’ve got 9 weeks to go!

What happens during the 31st week of pregnancy?

  • Take five: At week 31 there’s a zillion things going on it your inquiring young one’s mind, which is now capable of experiencing all five senses.
  • Wake up sleepyhead: Your baby is getting tons of shuteye, but they can actually wake up when you have something to eat, especially if it’s sugary or caffeinated.
  • Tour de uterus: Your little one is doing lots of moving around, and would you believe, is doing little pedaling motions with those tiny legs! Is future cycling stardom in their future?
  • Bathroom break: Thank goodness for amniotic fluid—for all that it gives your baby, it also takes away waste. At 31 weeks, your little one is urinating like a pro, and it all goes back into the amniotic fluid.

What should I be feeling at 31 weeks pregnant?

  • You may be feeling like your organs have all been displaced, and as a matter of fact, you’re right! With baby’s growth going into overdrive, it will be a relief to get some of that breathing room back as they begin the process of reposition for birth. You may feel shortness of breath, which is nothing to worry about unless it gets severe (at which point, give your doctor a call). If you’re feeling winded, sit or rest until it subsides. By birth, the pressure on your lungs and organs will dissipate, so you can breathe a sigh of relief (if you’ll pardon the pun!)
  • At this point, walking has become waddling, you’ll have swelling in your legs and feet (especially if you’re pregnant in warmer weather) and sleeping may become increasingly difficult.  While it’s going to be a little uncomfortable for the next couple months, in nine weeks you’ll have a new love in your life!
  • With that in mind, if you experience sudden facial or hand swelling, call your healthcare provider immediately, as it could be an indicator of something more serious. Facial swelling, changes in vision and headaches could be a sign of something called preeclampsia.

How big is your baby at 31 weeks pregnant?

Week 31 pregnancy symptoms

During week 31 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 31 pregnancy symptoms

  1. The pressure on your bladder will make you feel like peeing constantly (and you’ll need to go!)
  2. All the weight you’re carrying out front will be straining your back, causing muscle strains.
  3. With the increased girth, you’re like a bull in a china shop in terms of clumsiness.
  4. Somehow the pregnancy brain memory lapses and vagueness has doubled down, so you may want to take notes or keep a journal as you’re left wondering what you wanted to say a minute ago.
  5. It’s hard to sleep, and then when you’re awake, your head hurts. Stay hydrated and have frequent healthy snacks. Generally speaking, taking recommended doses of acetaminophen is permitted, unless your doc says otherwise.

4 expert week 31 tips for a healthy and safe pregnancy

Being 31 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.

  • All my bags are packed: Review your packing checklist get you bag ready with the essentials for your hospital stay. Be sure to keep it in a handy place and share the bag’s location with your partner or person that will be with you in the birthing room.
  • Soothe those aches: Do basic stretches to stop your neck and head aching. Massages also help, and baths are safe during pregnancy. For an added muscle-soother, try Epsom salts, but don’t soak for more than 15 minutes. It’s also very important to keep your core body temperature below 101°F, so keep a thermometer on hand before getting in the tub. If that’s too much to keep track of, opt for a foot bath, which is also a safe option.
  • Making waves: Swimming is another safe option for a weightless feeling and healthy movement to help with those aches. Many women find that the feeling of floating is soothing for both body and mind.
  • Making gains: You should be gaining about a pound a week during your third trimester, but don’t be obsessed with the scale. While some women feel uncomfortable with size changes during pregnancy, try to remember that weight gain is completely natural and healthy for you and your baby. And follow trusted sources on what to eat, as there’s a slew of pregnancy nutrition myths out there. As long as you’re eating a healthy diet and doing practicing a pregnancy-safe exercise routine, you’re taking steps to set yourself up for success for you and your baby. Your doctor will let you know they have any concerns.
