In the third trimester, many expectant mothers sleep less well.
The belly takes up more space, changing positions becomes more difficult, nocturnal awakenings are more frequent, and some pain may appear in the back, hips, or pelvis.
If you're wondering how to sleep comfortably in the third trimester without pain, the goal isn't to find a perfect position.
Rather, the goal is to better support your body, reduce tension, and make your nights more comfortable.

Why do we sleep less well in the 3rd trimester?
Late in pregnancy, several factors can disturb sleep:
- larger belly;
- more frequent need to urinate;
- back, pelvic, or hip pain;
- reflux or digestive discomfort;
- baby's movements;
- difficulty turning over;
- accumulated fatigue;
- stress or anticipation of childbirth.
These sleep disturbances are common during pregnancy. They don't necessarily mean there's a problem, but they can really impact daily life.
What is the best sleeping position for pregnant women?
Late in pregnancy, health organizations generally recommend sleeping on your side.
Sleeping on your side can be more comfortable when your belly gets heavy. This position also helps avoid lying on your back for extended periods late in pregnancy.
The left side is often advised, but the right side is also considered acceptable by many medical sources. The most important thing is to find a comfortable position and not intentionally stay on your back for a long time if it bothers you.
What if I wake up on my back?
This is a very common question.
If you wake up on your back during the night, there's no need to panic.
Simply reposition yourself gently on your side. Many women naturally change positions during sleep, and the goal is not to create anxiety around your nights.
You can also place a pillow behind your back to limit unintentional turning.
How to sleep during pregnancy with back pain?
Back pain during pregnancy at night is common, especially in the third trimester.
A few simple steps can help:
- sleep on your side;
- place a pillow between your knees;
- gently support your belly;
- avoid sudden twists;
- get up gradually;
- use multiple supports around your body.
Good support can sometimes reduce tension felt in the lower back.
Hip pain during pregnancy at night: what to do?
Some expectant mothers primarily experience hip pain when sleeping on their side.
To improve comfort, you can try:
- changing sides during the night;
- placing a pillow between your knees;
- avoiding crossing your legs too much;
- supporting your belly with a pillow;
- adding support behind your back.
The goal is to better distribute pressure points.
How to turn over more easily in bed?
In the third trimester, turning over can become difficult.
To limit tension:
- slightly bend your knees;
- keep your legs close together;
- turn gradually;
- avoid sudden movements;
- use your arms to assist the movement.
If you also have pelvic pain, these small actions can make a real difference.

Is a pregnancy pillow really useful?
A pregnancy pillow is not essential for all women.
But many expectant mothers find that it improves their comfort, especially in the third trimester.
It can help to:
- support the belly;
- prop up the back;
- support the legs;
- reduce some tensions;
- make the side position more comfortable.
A nursing pillow can also be used during pregnancy to support the body at night.
Can a pregnancy belt help you sleep better?
A pregnancy support belt is not meant to replace rest or medical advice.
However, some women find that better support during the day improves their overall comfort, especially when standing, walking, or feeling a heavy belly.
Less accumulated tension during the day can sometimes help you feel more comfortable in the evening.
What to avoid
In the third trimester, try to avoid:
- intentionally staying on your back for a long time;
- getting up abruptly;
- sleeping without any support if you're in pain;
- forcing an uncomfortable position;
- making many rapid movements in bed;
- neglecting severe or unusual pain.
Sleep should remain a time for recovery, not a source of stress.
Warning signs: when to seek advice?
Consult quickly or seek medical advice if you experience:
✓ very intense pain;
✓ regular contractions;
✓ significant decrease in baby's movements;
✓ bleeding;
✓ fluid loss;
✓ unusual shortness of breath;
✓ chest pain;
✓ severe headaches;
✓ sudden swelling of the face or hands;
✓ feeling that something is wrong.
When in doubt, it is always better to ask for advice from a midwife, a doctor, or the maternity hospital.

Sleeping on your side is generally recommended late in pregnancy. The left side is often advised, but the right side can also be suitable.
Is it serious to sleep on your back while pregnant?
Intentionally staying on your back for a long time late in pregnancy is generally not recommended. But if you wake up on your back, there's no need to panic: simply reposition yourself on your side.
Why do my hips hurt at night when I'm pregnant?
The weight of the belly, the side sleeping position, and pelvic changes can increase pressure points in the hips.
How to sleep pregnant with a pillow?
You can place a pillow between your knees, under your belly, or behind your back to better support your body.
