Round ligament pain during pregnancy is a common, usually harmless sharp or stabbing pain in the lower belly or groin caused by the stretching ligaments that support your growing uterus.

What is round ligament pain?

The round ligaments are rope‑like bands of tissue that help hold the uterus in place; as the uterus grows in pregnancy, these ligaments stretch, thicken, and can spasm, which causes pain. This pain is considered a normal pregnancy discomfort and does not harm you or the baby, even though it can feel quite intense in the moment.

What does it feel like?

Many people describe it as a sudden sharp, jabbing, or stabbing pain on one or both sides of the lower belly that may shoot into the groin or hip area. It can also feel like a brief pulling or stretching sensation, or a dull nagging ache that comes and goes depending on your activity.

When does it usually happen?

Round ligament pain most often starts in the second trimester, when the uterus grows more quickly, but some may notice it a bit earlier, especially in later pregnancies. It often flares with sudden movements such as rolling over in bed, standing up quickly, coughing, sneezing, laughing, or sudden turns while walking.

Why does it happen?

  • The growing uterus stretches the round ligaments, putting them under extra tension.
  • Pregnancy hormones make ligaments looser and more elastic, which can make them more prone to being overstretched or going into spasm.
  • Quick movements make the already‑stretched ligaments tighten suddenly, which triggers that sharp, brief pain.
  • In some cases, enlarged veins (varicosities) along the round ligament can add to pain or a heavy feeling in the groin.

Is it dangerous?

In most cases, round ligament pain is benign and just part of normal body changes during pregnancy. However, any new, severe, or persistent pain in pregnancy should be discussed with your healthcare provider to rule out other causes like preterm labor, appendicitis, urinary issues, or ovarian problems.

Warning signs – call your doctor or go to urgent care if:

  • Pain is severe, constant, or getting worse instead of coming in brief bursts.
  • You have pain with vaginal bleeding, fluid leakage, contractions, or strong tightening of the uterus.
  • You have pain with fever, chills, burning when you pee, vomiting, or trouble breathing.
  • One side of the abdomen is very tender with rigid muscles or you just feel that “something isn’t right.”

What helps relieve round ligament pain?

Common at‑home strategies include:

  • Changing positions slowly (for example, roll to your side before sitting up from lying).
  • Resting when the pain hits; lying on the side with knees bent can reduce strain on the ligaments.
  • Using a warm (not hot) compress or warm shower on the lower belly or hips.
  • Gentle stretching and prenatal yoga, or pelvic tilts and hip stretches recommended by a provider or physiotherapist.
  • Wearing a maternity or belly support band during walking or standing.
  • Avoiding sudden twisting, high‑impact exercise, or quick changes in direction when walking.

Only use pain medication that your prenatal provider has said is safe for you in pregnancy.

Mini “story” example

Imagine you’re in your second trimester, you roll over quickly in bed, and suddenly feel a sharp stab low on one side of your belly that makes you freeze for a few seconds. The pain eases when you lie still for a minute, and by the time you slowly get up, it has faded to almost nothing—that pattern is very typical of round ligament pain.
