How Big Is Your Baby at 33 Weeks?

Your baby is 17.2 inches long and weighs 4.2 pounds this week. That’s about the size of a lunch box.

Here’s what else to know when you’re 33 weeks pregnant:

Your Baby’s Development at 33 Weeks

Your baby is continuing to ready for their big debut, becoming adding fat layers, hardening up bones and strengthening their immune system. Here are the details on what’s happening with baby at 33 weeks.

  • Hard bones: Your little one’s bones are hardening. But the skull will still be soft at birth to allow the head to move through the birth canal—aka your vagina. Know that babies have soft spots called fontanelles between parts of their skull. They will close in a couple of years (yes, years), and that’s why you have to be gentle with the head post-birth.
  • Baby fat: The babe is also starting to chub out by adding fat on their arms and legs. Sure, it makes them extra adorable (less wrinkly too), but it mainly helps them regulate their body temperature in the early weeks of life.
  • Peach fuzz: The soft layer of hair called lanugo is falling off this week, though some may be left on the baby’s shoulders or back at birth.
  • Immune system: You’re passing antibodies to your baby to prep their developing immune system to fight off germs once they reach the outside world.

💛 Congratulations 💛

You only have seven weeks left!

Your Body: 33 Weeks Pregnant Symptoms

From more discharge to feeling Braxton Hicks contractions, you and your body are experiencing a lot as you prepare for labor. Here are some of the main symptoms you may be experiencing at 33 weeks pregnant:

  • Overheating: Feeling toasty? Your baby is actually radiating body heat, so many pregnant moms have a higher skin temperature during the third trimester.
  • Vaginal discharge: It’s very common to have more white-colored discharge during the third trimester because of your increased estrogen levels. Look out for an increase in discharge, but be aware of any big changes. If there are some streaks of blood and the discharge is particularly gelatinous, almost like a jellyfish on the beach, it may be your mucus plug coming out, which is an early sign of labor. If it’s a clear, thin fluid that comes out in a trickle or a gush—that could be amniotic fluid leaking, and means you should call you healthcare provider immediately.
  • Braxton Hicks contractions: You may be feeling these practice contractions—a tightening of the belly that isn’t regular or often—here and there, as you body preps to give birth. Stay hydrated to help prevent them from becoming too uncomfortable.
  • Carpal tunnel: Pregnant women retain fluids, which causes swelling and puts pressure, well, on a lot of things…but notably on a nerve in and around your wrist. This can cause pain, numbness and/or tingling in the hand and fingers called carpal tunnel syndrome. And you may be more likely to get it if you use your hands a lot throughout the day. Late in pregnancy, carpal tunnel can worsen; wearing a wrist splint or hand brace could help. Talk to your doctor about your options. Thankfully, carpal tunnel is likely to go away once you give birth.
  • Baby brain: Feeling forgetful? There’s no scientific evidence that pregnant women experience memory loss or brain fog because they’re pregnant. You probably just have a lot on your mind. (Can you say understatement?) Plus, you could be sleep deprived, stressed or moody—or all of the above. So baby brain can feel real. Be kind to yourself, reminding yourself that it’s okay not to be on top of every little thing. And maybe make some lists so your brain doesn’t have to retain it all.
  • Sex and contractions: As long as your doctor gives the okay, sex is perfectly safe until the end of your pregnancy. But know this: an orgasm can give you contractions. But don’t freak out; it’s totally normal—in fact, you may have been having them all along but are only noticing them now that your belly’s bigger. Post-coital contractions aren’t likely to put you into labor, so enjoy yourself if you feel like it.

Fun Fact

More babies are born in September than any other month. Feburary is the month with the least number of births. (Maybe because it’s the shortest month.)

Your Life at 33 Weeks Pregnant

With less than two months to go, you’ve hit the stage where it’s all about making sure you’re comfortable and rested. Here are some ideas to help.

  • Top tip: Maternity leave should be about recovering from childbirth and bonding with your brand-new little human, not worrying about what’s going to happen when you go back to work. If you can, take the time to finalize childcare plans now so you can rest easy during your time off.
  • Treat yourself: You know what’s great about slippers? No matter how swollen your feet get, they’ll always fit and feel good. Whether you like shearling-lined, memory foam or sandals, a good pair of slippers will be a treat for your feet today and once the baby arrives. As an added bonus, they’ll also come in handy when you’re laboring in the delivery room, as well as when you’re recovering and home with baby.
  • Postpartum prep: Even if you’re having your baby in a hospital or birth clinic, it’s a good idea to prep your home bed for, well, some post-birth bodily fluids. A bed pad will keep your sheets clean in case of any unexpected leaks while you sleep.
  • Great gear: You probably have a pregnancy pillow by now, but consider the wedge pillow too. (Hey, being a comfy pregnant person requires a lot of pillows!) Heartburn ramps up during the third trimester as your growing baby puts pressure on your stomach. If acid reflux and indigestion keep you up at night, the wedge pillow can bring major relief. It can also double as a helpful prop for breastfeeding in bed if you decide to nurse.

Managing Multiple Registries?

Your 33 Weeks Pregnant Belly

At 33 weeks pregnant, weight gain should continue to be about a pound a week. You’ll stick to this rate all the way up to your due date (and beyond, if you go that far!). By now, you may have gained about 22 to 28 pounds total, so you’re probably feeling heavy and may have slowed down a bit. You have may even started the infamous pregnancy waddle.

Amniotic fluid levels out right about now, and since your baby keeps growing, you’ll have more baby than fluid. Less of that padding can mean baby’s kicks and jabs feel sharp and unmistakable. Pay attention to the movements as much as you can, and call your healthcare provider right away if you notice a decrease in them.

33 Weeks Pregnant Checklist
