33 Weeks Pregnant: Your Baby’s Development

Here are some of your baby’s amazing developments at 33 weeks pregnant:

  • At this point in your pregnancy, your baby’s brain is working hard, with all five senses working now!

  • Your little one can now hear some of what’s happening outside the womb. When they hear your voice, their heart rate may slow down, meaning they’re calmer.

  • They’re also able to distinguish light from dark in their small environment. In fact, your baby’s eyes are developed enough that the pupils respond to light changes.

  • Your baby is rapidly gaining weight at 33 weeks pregnant, and they’ll continue to do so until their due date. They probably won’t grow much longer, though.

  • In addition to these important fetal developments, at around 33 weeks pregnant, your baby's bones are starting to become harder, although their skull is still soft and flexible enough to allow it to fit through the birth canal. Don’t worry if their head looks a little misshapen at birth because the soft spots on their skull will fuse together and harden sometime in the first two years of their life.

  • If not at 33 weeks pregnant, then at some point in the last few weeks of your pregnancy, your healthcare provider will try to determine your baby’s position. If your provider suspects your baby may be in the breech position—meaning either buttocks down or buttocks and feet down—they may suggest an ultrasound to find out for sure.

  • If you’re 33 weeks pregnant with twins, find out more about being pregnant with multiples.

Your Body at 33 Weeks Pregnant

At this point in your pregnancy, you may find that sleep is eluding you. With your increased size and protruding belly, at 33 weeks pregnant, sleeping through the night may be more difficult, which might leave you feeling exhausted.

Try to make your bed as comfortable as possible, adding pillows for your legs and abdomen. To feel a little more rested, take daytime naps whenever possible. Lower back pain and pelvic pressure may be a cause of discomfort around 33 weeks pregnant due to the size of your belly. If your baby has “dropped” into a lower position in your pelvis at 33 weeks pregnant, this can lead to increased pressure not only in the pelvic area but also in the hips and bladder, and your belly may appear lower. Pelvic girdle pain may also cause your pelvic area, hips, groin, and/or lower back to hurt when you walk around 33 weeks pregnant.

You can do some gentle backbends to help ease the discomfort: As you stand upright, place your hands on your back and bend slightly backwards (about 15 to 20 degrees). Repeat this movement a few times, as needed.

Consult your healthcare provider for more information on how to exercise and stretch your back and for other ways to reduce or manage back pain.

33 Weeks Pregnant: Your Symptoms

Here are some common symptoms that you may be experiencing around 33 weeks pregnant:

  • Frequent urination. Your growing baby could be moving lower, putting some unwelcome pressure on your bladder. This means you’re probably peeing more often, maybe even when you laugh, cough, or sneeze. There’s not much you can do to relieve this symptom, but if you are experiencing bladder leakage, try wearing a panty liner to keep you dry in case of minor accidents. Don't cut back on drinking water, because staying hydrated is especially important. It can be helpful, though, to make sure that you use the bathroom before you leave the house or head into a meeting at work, for example.

  • Braxton Hicks contractions. You’re getting closer to your due date, so those “practice” contractions may be kicking into high gear and getting stronger. If you feel what may be symptoms of true labour contractions at 33 weeks pregnant, it’s a good idea to time them; typical labour contractions will last up to 90 seconds and will come and go at regular intervals. Braxton Hicks contractions are more likely to occur in the evening and after physical activity like exercise or sex, and they subside when you move or change positions. If you're concerned about the symptoms you are experiencing at 33 weeks pregnant, contact your healthcare provider immediately.

  • Leg swelling. Your growing uterus can place pressure on the major veins that move blood from your lower body to your heart, which can sometimes lead to swollen legs. If you experience swelling in your legs or feet, avoid standing for long periods. Whenever possible, elevate your feet to help improve circulation. Comfortable shoes and support socks or stockings can also help with this.

  • Carpal tunnel syndrome. Swelling can also place pressure on the nerves in your wrists and hands, which leads some pregnant people to develop carpal tunnel syndrome. This affects the bones and ligaments in the wrist and can cause discomfort, including numbness and a tingling feeling in the hands. These symptoms usually subside after you give birth, and the discomfort should disappear along with the swelling. Wrist braces or splints could help make you more comfortable, and your healthcare provider may have additional advice on what to do.

  • Itchy skin. Itchy skin is a common symptom that many pregnant people experience at 33 weeks and later in pregnancy. Over the past few months, your skin has been expanding across your belly and breasts, and this can cause dryness and irritation. Make sure you’re applying a gentle moisturizer day and night, and if the itchy feeling persists, consider taking a bath with cornstarch to help ease the unpleasant sensation. If you experience extreme itchiness or develop a rash, consult your healthcare provider.

  • Abdominal cramping. If you experience abdominal cramps around 33 weeks pregnant, this may occasionally be a symptom or sign of preterm labour, so it’s helpful to be familiar with the signs and symptoms not to ignore. Sometimes, but not always, this cramping is accompanied by diarrhoea. If you notice either of these symptoms, let your healthcare provider know right away.

How Big Is a Pregnant Belly at 33 Weeks?

Your growing baby means that your uterus is also expanding. If your fundal height was measured at 33 weeks, it would likely be around 33 centimetres (13 inches)—from the top of your pubic bone to the top of your uterus. But remember, every pregnancy bump is different!

You may even begin to feel more pressure in your lower body as your baby starts to settle into a lower position in your pelvis around 33 weeks pregnant or in the next few weeks.

33 Weeks Pregnant: Things to Consider

From birthing positions to car seats, there are many things to consider and take care of during this period:

  • With your due date approaching, you might want to investigate some labour and birthing positions that may help make delivering your baby a bit more comfortable. Do some research to find out more about the options available to you, like birthing chairs, stools, balls, or even pools or tubs for labouring in water. Talk to your healthcare provider to find out what your hospital or birthing centre can offer you. Naturally, you won’t know what feels best until you’re actually in labour but take some time now to explore your choices.

  • If you have older children, think about who will watch them when you are in labour and take care of them during your hospital stay. Consider asking a family member to be on standby or arrange a babysitter who can be available at short notice.

  • If you get around by car, you’ll need an approved car safety seat for when your baby arrives. It needs to be rear-facing and properly installed in the backseat of your vehicle. All car seats should meet the current Canadian Motor Vehicle Safety Standards, have a national safety mark, and have an expiration date (though not required by law).
