Round ligament pain is one of the most common discomforts of pregnancy, and the good news is that several simple strategies can reduce it significantly. The pain typically shows up during the second trimester (weeks 14 through 27), when your uterus is growing rapidly and the two ligaments that help anchor it stretch to keep up. Relief comes from a combination of movement modifications, gentle stretching, supportive gear, and smart positioning throughout the day.
What’s Actually Happening
You have two round ligaments, one on each side of your uterus. They run from the top corners of your uterus, travel through your groin, and eventually connect to the tissue of your labia. Before pregnancy, these ligaments are short and firm. As your uterus grows heavier, they stretch and contract to support it, which can cause sharp, stabbing pain or a dull ache on one or both sides of your lower belly or groin.
The pain is often triggered by sudden movements: sneezing, coughing, laughing, rolling over in bed, or standing up quickly. It typically lasts only a few seconds to a couple of minutes, then resolves on its own. The exact week it peaks varies from person to person, but the rapid uterine growth of the second trimester is when most people feel it the worst.
Modify Sudden Movements First
The single most effective thing you can do is slow down transitions. When you need to stand up from a chair or get out of bed, roll to your side first and push up with your arms rather than engaging your core in one quick motion. This reduces the sudden pull on the ligaments that triggers the sharpest pain.
If you feel a sneeze or cough coming on, bend your hips slightly and bring your knees toward your chest (or just lean forward). This gives the ligaments some slack so the sudden abdominal contraction doesn’t yank on them. The same applies to laughing. It sounds strange, but pre-flexing your hips before a big sneeze can prevent the stabbing sensation entirely for many people.
Stretches That Relieve Tension
Gentle stretching helps keep the muscles around the ligaments loose, which reduces the frequency and intensity of pain episodes.
Cat-cow stretch: Get on your hands and knees with your shoulders over your wrists and hips over your knees. As you exhale, arch your back toward the ceiling and drop your head (cat). As you inhale, let your belly drop toward the floor and lift your head gently (cow). Hold each position for a few breaths before switching. Repeat five to ten times. This mobilizes the pelvis and spine without putting direct strain on the ligaments.
Pelvic circles: Sit on an exercise ball (or stand with feet shoulder-width apart) and gently rotate your hips in a circular motion, first clockwise, then counterclockwise. This loosens the muscles surrounding the pelvis and helps relieve tension that builds up during the day. If you’re using an exercise ball, you can also try the “pelvic clock”: imagine your pelvis sitting on a clock face and tilt toward each number in sequence, creating small, controlled arcs. Focus on engaging your abs lightly and keeping your spine long throughout.
These stretches work best as a daily habit rather than a rescue measure. A few minutes in the morning and evening can keep the surrounding muscles from tightening up overnight or during long periods of sitting.
Support Belts and Belly Bands
Maternity support garments work by lifting some of the weight of your growing uterus off the ligaments and pelvis. A 2018 study of 90 pregnant women found that wearing a pregnancy support garment slightly improved posture across all trimesters. Importantly, these garments will not weaken your muscles even if you wear them for extended periods, so you can use them all day if they help.
There are a few types to consider:
- Belly bands sit low on your abdomen and pull your baby’s weight slightly off your pelvis. These are the most common choice for round ligament pain specifically, since they directly reduce the downward pull that strains the ligaments.
- Sacroiliac support belts wrap around your hips lower than belly bands and provide compressive support to the joints. These are better if your pain extends into your hips or lower back. Look for products labeled “SI belt” or “sacroiliac support belt.”
- Belly cradles combine a belly band with crossed upper-back straps. These are often used when carrying multiples or when you need extra support, though they can be more complicated to put on alone.
Belts tend to be more snug and work best under clothing. If you notice skin irritation, wearing them over a thin layer of fabric usually solves the problem.
Sleeping Positions and Pillow Setup
Nighttime is when round ligament pain often catches people off guard, especially when rolling over. Sleeping on your left side is generally recommended during pregnancy, and the right pillow arrangement can take pressure off the ligaments throughout the night.
Place a pillow (or several) between your knees, feet, and thighs so your upper leg sits level with your pelvis and mirrors the angle of your bottom leg. This keeps your spine neutral and prevents your top hip from pulling forward and stretching the ligament. A small rolled washcloth or thin pillow tucked under your belly supports the weight of your uterus so the ligaments aren’t bearing the load while you sleep. If you also feel back discomfort, placing a rolled towel between your ribs and hips fills the gap and keeps your spine from sagging.
For getting out of bed, roll fully onto your side, let your legs drop off the edge, and push up with your arms. Avoid sitting straight up from a lying position, which fires the abdominal muscles suddenly and tugs hard on the round ligaments.
When Pelvic Floor Physical Therapy Helps
If stretching and daily modifications aren’t enough, a pelvic floor physical therapist can offer more targeted relief. These specialists use hands-on techniques like myofascial release and gentle massage to reduce tension in the muscles surrounding the round ligaments. They also design customized exercise programs that strengthen your pelvic floor and deep core muscles, giving your uterus more structural support and reducing the strain on the ligaments themselves.
Breathing exercises and manual therapy can also help relax the entire pelvic region. This is especially worth considering if your pain is persistent, if it limits your ability to walk comfortably, or if it keeps waking you up at night despite good pillow support.
Acetaminophen for Pain Relief
Among over-the-counter pain relievers, acetaminophen (Tylenol) remains the safest option during pregnancy. Both aspirin and ibuprofen carry well-documented risks to the fetus, so they’re generally avoided. That said, the FDA advises clinicians to minimize acetaminophen use during pregnancy when possible, treating it as a tool for meaningful discomfort rather than a daily habit. For most round ligament pain episodes, physical strategies like repositioning or applying warmth to the area resolve the pain within minutes, making medication unnecessary.
Pain That Isn’t Round Ligament Pain
Round ligament pain resolves on its own within a couple of minutes. If your pain continues beyond that, it may be something else. Preterm labor can feel similar to round ligament pain, but the key difference is that preterm labor contractions keep going rather than stopping quickly. Contact your provider if lower abdominal pain is persistent or if it comes with any of these: fever or chills, vaginal bleeding, pain during urination, or difficulty walking. Severe stomach pain during pregnancy can also signal other conditions, including appendicitis, a hernia, or placental abruption, all of which need prompt evaluation.
