Pregnant moms will tell you that eventually, pregnancy back pain strikes – hard! It certainly makes the list of the top 5 pains of pregnancy and for obvious reasons. You’re literally carrying a whole separate person in your front and that puts a strain on your back. However, the timing of pregnancy back pain couldn’t be worse! For most of us, back pain comes at night so if you’ve felt really bad back pain at night while pregnant, you’re not alone. Here’s why it’s happening and why the U-shaped pregnancy pillow is the best option for back pain at night.

Why does your back hurt at night during pregnancy?

Studies have been done to answer this question for pregnant women and here is the main theory…

“Low back pain during pregnancy, especially pain that worsens at night and is severe enough to wake the patient up, is the result of venous engorgement in the pelvis. The expanding uterus presses on the vena cava, particularly at night when the patient is lying down. This combined with the increased fluid volume from fluid retention during pregnancy leads to venous congestion and hypoxia in the pelvic and lumbar spine.” (from US National Library of Medicine
National Institutes of Health

In a nutshell, you guessed it, your body is changing and putting a heavy burden on your pelvis and spine.

What Helps Back Pain at Night During Pregnancy?

Here’s a quick list of doctor-recommended solutions for back pain that strikes at night.

  1. Try to keep your posture in mind. Since your changing body may cause you to overcompensate for the weight in your front, you may find yourself leaning backward, which puts a strain on your back. To combat this tendency, think about keeping your shoulders and chest straight and upright and sit with a pillow at your back to keep you sitting upright as well.
  2. Sleep on your side. According to, doctors highly recommend sleeping on your side during pregnancy to provide optimal circulation to your and your baby. Furthermore, side sleeping “also places the least pressure on your veins and internal organs. Sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and your baby. Plus good circulation helps reduce potential swelling, varicose veins in your legs and hemorrhoids.”
  3. Make sure you’re doing limited exercises to keep your back muscles strong. Again, there is helpful information about pregnancy exercises found on American Pregnancy website, and there you’ll be able to find guidance on the best pregnancy exercises to help pregnancy discomforts, including back pain.
