Pregnancy brings about many changes in a woman's body, which can affect her daily habits, including her sleep. One common concern for expectant mothers is finding a comfortable and safe sleeping position. Sleeping on the stomach while pregnant is generally considered safe during the early stages of pregnancy, but as the pregnancy progresses, it may become uncomfortable. Research suggests that it is safe to sleep in whichever position one prefers until around 30 weeks of gestation. In the third trimester, sleeping on the side, particularly the left side, is recommended as it improves blood flow to the heart and the baby.

It is safe to sleep on your stomach during the first trimester
Sleeping on your stomach may, however, become uncomfortable as your pregnancy progresses. This is due to the growth of your abdomen, which raises the torso and alters the natural curvature of the spine. It may also cause neck and shoulder problems, such as pain, stiffness, and soreness. Some people may also experience lower back pain and pelvic girdle pain during pregnancy, which can make it more difficult to sleep.
If you find that sleeping on your stomach becomes uncomfortable, you can try sleeping on your side, preferably your left side. This is because a large vein, known as the inferior vena cava (IVC), runs parallel to the spine on the right side. The IVC carries deoxygenated blood from the lower body back to the right side of the heart for oxygenation. By lying on your left side, you allow for optimal blood flow to the heart and nutrients to reach the fetus.
It is important to note that, in the latter stages of pregnancy, specifically after 28 weeks, sleeping on your back is associated with an increased risk of adverse symptoms and outcomes, including stillbirth. So, while it is safe to sleep on your stomach during the first trimester, you may need to adjust your sleeping position as your pregnancy progresses.

Sleeping on your stomach during pregnancy can cause back and neck pain
Sleeping on your stomach during pregnancy is generally considered safe and won't harm your baby. However, as your pregnancy progresses and your bump grows, sleeping on your stomach may cause back and neck pain. This is because your growing abdomen raises your torso, altering the natural curvature of your spine.
During the early stages of pregnancy, many people continue to sleep on their stomachs without discomfort. Some people find that sleeping half on their stomach and half on their side is more comfortable. However, as the pregnancy progresses, sleeping on your stomach may become uncomfortable and challenging due to the growing bump.
As your belly grows, sleeping on your stomach can put strain on your neck and spine, leading to back and neck pain. It is important to listen to your body and adjust your sleeping position as needed. Most people will naturally transition to sleeping on their sides as their pregnancy progresses.
Doctors typically recommend sleeping on your side during pregnancy, especially in the latter stages. Sleeping on your left side is often considered ideal as it ensures optimal blood flow to the baby. This is because the inferior vena cava (IVC), a large vein that carries deoxygenated blood back to the heart, runs parallel to the spine on the right side. Sleeping on your left side allows for optimal blood flow to the heart and ensures that oxygenated blood, nutrients, and blood reach the fetus.
To enhance comfort while sleeping on your side, you can use pillows for support. Place a pillow between your knees to keep your spine aligned, and use a supportive pillow under your head and neck. You can also tuck a small cushion or rolled-up towel under your abdomen for added support. Body pillows can be particularly helpful for people experiencing back pain during pregnancy.

Sleeping on your left side is the ideal position during pregnancy
Pregnancy can cause difficulty sleeping, and certain sleeping positions are safer than others. Research suggests that it is safe for people to sleep in whichever position they prefer until around 30 weeks of gestation. However, in the latter stages of pregnancy, it is recommended to try to sleep on the side, preferably the left side, for optimal blood flow to the fetus.
A 2019 review suggests that sleeping on either side during pregnancy is safe. However, sleeping on the left side is considered the "ideal" sleeping position during pregnancy, mostly due to blood flow. A large vein, known as the inferior vena cava (IVC), runs parallel to the spine on the right side. The IVC carries deoxygenated blood from the lower body and back to the right side of the heart for oxygenation. As the IVC is to the right of the spine, lying on the left side may allow optimal blood flow to the heart and, in turn, optimal blood flow, and nutrients, to the fetus.
Sleeping on the left side also takes the pressure off the liver and kidneys, meaning more room for them to function properly, helping with swelling issues in the hands, ankles, and feet. Additionally, in the third trimester, sleeping on the side has been shown to be the safest thing for the baby, including daytime naps. Research has shown that, in the third trimester, sleeping on the back increases the risk of stillbirth.
While sleeping on the left side is ideal, sleeping on the right side is also considered safe. However, there is a slight risk of compression issues with the IVC when sleeping on the right side. Ultimately, the most important thing is to find a comfortable sleeping position. For those who prefer sleeping on their stomach, this may become uncomfortable as the abdomen grows and raises the torso, altering the natural curvature of the spine. Some people may find it helpful to use a stomach sleeping pillow with an area cut out for the belly, or to slip a pillow between their legs when sleeping on their side.

Sleeping on your back during pregnancy can cause adverse outcomes
Sleeping on your stomach during pregnancy may become uncomfortable as your abdomen grows, altering the natural curvature of your spine. Research suggests that it is safe to sleep in any position until around 28 to 30 weeks of gestation. However, in the latter stages of pregnancy, sleeping on your side is recommended, with the left side considered ideal for optimal blood flow to the fetus.
Sleeping on your back during pregnancy, especially for long stretches, can cause adverse outcomes. As the uterus grows, it can put pressure on the aorta and a large vein called the inferior vena cava (IVC), disrupting blood flow to the heart and potentially reducing blood flow to the fetus. This reduced blood flow can lead to decreased oxygen supply to the fetus, increasing the risk of complications such as preeclampsia, fetal growth problems, and, in rare cases, stillbirth.
While there is conflicting evidence regarding the link between sleeping position and stillbirth, some studies have found an association between sleeping on the back and an increased risk of stillbirth. However, it is important to note that waking up on your back occasionally is not a cause for concern, as long as you are doing your best to fall asleep on your side.
To ensure you are sleeping on your side, you can use pillows for support. Placing pillows behind your back can help prevent you from rolling onto your back, and a pillow between your legs can help keep your legs level and prevent pain. It is also recommended to pay attention to your sleep position during daytime naps, as well as at night.
Overall, while sleeping on your back during pregnancy can potentially cause adverse outcomes, the risk is relatively low, and getting enough sleep is crucial for both you and your baby's well-being.

Stomach sleepers can use pillows to support their abdomen and hips
Sleeping on your stomach while pregnant is generally considered safe during the early stages of pregnancy. However, as the pregnancy progresses, it may become uncomfortable to sleep on your stomach as your bump gets bigger and raises your torso, altering the natural curvature of your spine. Additionally, healthcare professionals typically recommend sleeping on the side, preferably the left side, from 28 weeks onward to ensure optimal blood flow to the fetus.
If you are a stomach sleeper, you can use pillows to support your abdomen and hips, making this position more comfortable. Here are some ways to do this:
- Place a pillow between your legs to ease discomfort in your hips and lower body.
- Use a full-body pillow or a pregnancy pillow, which are specifically designed to support pregnant sleepers.
- Try an orthopedic knee pillow made of memory foam for extra support and comfort.
- Place a pillow under your abdomen to provide support and keep you from rolling onto your back.
- Elevate your upper body with a pillow if you experience heartburn at night. Sleeping slightly upright may help relieve these symptoms.
While it is generally safe to sleep on your stomach during early pregnancy, it is important to listen to your body. If sleeping on your stomach becomes uncomfortable or if you have any concerns, consult with a healthcare provider to determine the best sleeping position for you.
