Pelvic pain during pregnancy is extraordinarily common, affecting roughly 45% of pregnant women overall and up to 60–70% in late pregnancy. The good news: most of it responds well to a combination of movement changes, targeted exercises, physical support, and simple adjustments to how you go about your day. Here’s what actually helps.
Why Pregnancy Causes Pelvic Pain
Your body produces a hormone called relaxin, primarily from the ovaries, that loosens the ligaments holding your pelvic joints together. This loosening is intentional: it gives your pelvis the flexibility it needs for delivery. But relaxin doesn’t just gently stretch ligaments. It actively breaks down the tough, fibrous tissue that normally keeps joints stiff and stable, which can leave the pubic joint at the front of your pelvis and the sacroiliac joints at the back shifting more than they should.
As your baby grows, the added weight pulls your center of gravity forward, forcing your pelvis and lower back to absorb more load with less structural support. That combination of looser joints and heavier demand is what produces the aching, stabbing, or grinding sensations in your pubic bone, groin, hips, or lower back. Pain typically appears before 20 weeks for about a third to half of women and tends to intensify as pregnancy progresses.
Exercises That Stabilize the Pelvis
The muscles around your pelvis can compensate for what your loosened ligaments can no longer do. Two exercises form the foundation of most physiotherapy programs for pelvic pain in pregnancy.
Pelvic tilts gently stretch your lower back and pelvis. Lie on your back with knees bent (or stand against a wall if lying flat is uncomfortable), then flatten the curve of your lower back by tilting your pelvis upward. Hold for a few seconds, release, and repeat. This works well as a warm-up before other movements and is particularly helpful if stiffness accompanies your pain.
Lower tummy exercises target the deep abdominal muscles that act like a sling supporting your baby’s weight. When these muscles are engaged, they reduce the strain transferred to your back and pelvis. On all fours, breathe in, then as you breathe out gently draw your lower belly up and in, holding for five to ten seconds without moving your back. The contraction should feel subtle, not like a crunch.
A controlled trial found that stabilizing exercises significantly reduced pelvic pain scores compared to standard advice alone, with measurable improvements in both morning and evening pain. Consistency matters more than intensity. A few minutes daily beats a longer session once a week.
How to Sleep With Less Pain
Nighttime is often the worst for pelvic pain because rolling over or shifting positions forces your loosened joints to twist under load. The most effective sleeping setup is lying on your side with a pillow between your knees. This keeps your hips aligned and prevents the top leg from pulling your pelvis into rotation.
As your belly grows, add a second pillow or a rolled-up towel under your bump to support its weight. Without that support, your abdomen sags forward and drags on both your lower back and pelvic joints. Some women find a full-length body pillow easier than managing multiple pillows. A Cochrane review found that a specially shaped sleeping pillow was one of the interventions with measurable benefit for pelvic girdle pain.
Pelvic Support Belts
Pelvic belts wrap around your hips (below your belly, not around your waist) and compress the pelvic joints to limit excessive movement. In pilot research, women wearing pelvic belts showed improvements in both pain and daily function over three weeks. Flexible belts appeared to reduce pain more effectively than rigid ones and were better tolerated.
That said, the evidence for belts used on their own is limited. In clinical practice, they’re almost always combined with exercises, and their individual contribution is hard to isolate. Think of a belt as a helpful addition to your routine rather than a standalone fix. If you try one, a physiotherapist can ensure it’s positioned correctly over the greater trochanters (the bony points at the sides of your hips) rather than sitting too high, where it won’t do much.
Daily Movement Adjustments
Small changes to how you move through your day can make a surprisingly large difference. The core principle is simple: keep your legs together and your pelvis symmetrical whenever possible.
- Getting out of bed: Roll onto your side, keep your knees together, and push up with your hands rather than twisting your torso.
- Stairs: Go one step at a time, leading with your stronger or less painful leg going up, and your more painful leg going down. Use a handrail.
- Standing: Distribute your weight evenly on both feet. If you’re standing for a while, place one foot on a low step or stool to reduce pelvic tilt.
- Sitting: Use a chair with good lumbar support and keep your feet flat on the floor. Avoid crossing your legs, which rotates the pelvis unevenly.
- Dressing: Sit down to put on pants, socks, or shoes rather than balancing on one leg.
- Lifting: Bend at your knees rather than your waist, and avoid carrying anything heavy on one side of your body.
These aren’t dramatic changes, but they prevent the repeated asymmetric loading that aggravates already-unstable joints throughout the day.
Acupuncture
Acupuncture has some of the strongest evidence among complementary therapies for pregnancy pelvic pain. In a controlled trial where one group received acupuncture, another received stabilizing exercises, and a control group received standard advice with a pelvic belt, the acupuncture group saw the largest pain reductions: 12 points lower in the morning and 27 points lower in the evening compared to controls. The exercise group also improved, but acupuncture outperformed it on pain scores.
Part of this may reflect the one-on-one attention an acupuncturist provides compared to group physiotherapy. Still, a Cochrane review listed acupuncture among the interventions with demonstrated benefit for pelvic girdle pain in pregnancy. If you have access to a practitioner experienced in treating pregnant patients, it’s a reasonable option to explore alongside exercise.
Pain Relief Medication
Acetaminophen (Tylenol) remains the recommended first-line pain reliever during pregnancy, according to the American College of Obstetricians and Gynecologists. The guidance is to use the lowest dose that helps, for the shortest time you need it. NSAIDs like ibuprofen should be avoided during pregnancy.
It’s worth noting that many women with significant pelvic girdle pain find acetaminophen only partially effective or not effective at all. This is common and doesn’t mean something is wrong. It simply means that a structural, joint-related pain often responds better to physical strategies (exercises, belts, movement modification) than to medication designed primarily for inflammation or fever. Acetaminophen can still take the edge off on particularly bad days.
What Pelvic Pain Doesn’t Mean
Pelvic girdle pain does not mean labor is approaching or progressing. It’s a musculoskeletal issue caused by joint laxity and load, not a sign of cervical change. However, certain symptoms alongside pelvic pain do warrant prompt attention: regular, timed contractions, vaginal bleeding, fluid leaking, or pelvic pressure that feels fundamentally different from your usual pain pattern. These could indicate preterm labor or other complications unrelated to pelvic girdle pain. The pain itself, even when severe, is not dangerous to your baby.
Water-Based Exercise
A Cochrane review identified water gymnastics as one of the beneficial interventions for pregnancy pelvic pain. Being in water offloads your joints by reducing the effective weight your pelvis has to carry, while the resistance of the water still allows you to strengthen the muscles around your hips and core. Swimming with a gentle breaststroke kick can aggravate the pubic joint for some women, so a flutter kick or simply walking in chest-deep water may feel better. Even floating with gentle leg movements provides relief for many women, particularly in the third trimester when land-based exercise becomes more difficult.
