Round ligament pain

If you’ve felt a sudden, sharp tug or a dull ache low down on one or both sides of your belly (or into your groin) when you move — getting up, rolling over in bed, coughing or sneezing — there’s a good chance it’s round ligament pain. It’s a common and harmless part of the second trimester in particular, though it can happen at other times too.

The round ligaments are two cords that support your uterus, running from its upper sides down into your groin. As your uterus grows, these ligaments stretch and thin out, and because they’re sensitive to sudden movement, a quick shift can make them contract sharply and give you that stabbing or pulling sensation. It usually lasts only a few seconds to a few minutes, and it’s more common on the right side. It’s a stretching pain, not a sign that anything is wrong.

Because it’s set off by sudden movements, the main way to ease it is to move more gently and gradually. Change position slowly, especially when getting out of bed or up from a chair. If you feel a sneeze or cough coming, bend and flex your hips a little, or support your bump, to take the strain off the ligaments. Some people find gentle stretching, a warm (not hot) compress, a warm bath, or a maternity support belt help. Resting and changing position when it strikes usually settles it quickly, and prenatal yoga or a women’s-health physio can help if it’s a regular bother.

The main thing is being able to tell everyday round ligament pain apart from something that needs checking. Round ligament pain is brief, movement-related, and eases when you rest or change position. Contact your midwife or maternity unit if your tummy pain is instead:

• Severe, constant, or not eased by rest
• Accompanied by bleeding, or fluid leaking from your vagina
• Accompanied by regular tightening or cramping (which could be contractions), especially before 37 weeks
• Accompanied by a fever, chills, or pain or burning when you wee
• Accompanied by a change in your baby’s movements

Those are the signs that it’s worth a phone call rather than just riding it out.

It can be reassuring to remember how mechanical this pain is: it’s literally the ligaments that anchor your uterus being tugged as everything grows and shifts. That’s why it so often strikes with a specific movement — rolling over, standing up fast, a sneeze — rather than out of nowhere. Once you connect the twinge to the movement, it tends to feel a lot less alarming, and slowing down for those trigger moments genuinely reduces how often it catches you.

But for the classic quick, sharp twinge that comes with a sudden move and then fades, be reassured it’s simply your body making room. Take corners slowly, support your bump, and know it eases as your pregnancy progresses.
