33 Weeks Pregnant: Your Baby’s Development
Here are some of your baby’s amazing developments at 33 weeks pregnant:
How Many Months Is 33 Weeks Pregnant?
So, what is 33 weeks pregnant in months? You’re likely in your eighth month at this point—there are a couple of different ways to group the weeks of pregnancy into months, so this can vary.
Baby's Size at 33 Weeks Pregnant
How big is your baby at 33 weeks? This week, the average baby is about the size of a small pineapple, and your little one is putting on weight quickly now, about a half pound (0.22kg) a week. At the end of the previous week, your baby may have weighed more than 1.8 kilograms (4 pounds), and they’re likely measuring around 43 centimetres (17 inches) in length.

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.
