Round ligament pain is a common pregnancy symptom that most often begins in the second trimester, although some people notice it earlier or later. It usually feels like a sharp jab or pulling ache low in the belly or groin, often lasts only seconds to a few minutes, and is linked to the ligaments that support your growing uterus stretching. Typical round ligament pain is generally considered harmless and does not usually indicate a problem with the pregnancy. This guide covers how long it lasts, what helps, and which symptoms need a call to your doctor.

What Round Ligament Pain Feels Like

Round ligament pain shows up as a quick, sharp jab or a deep pulling ache low in your belly, usually on one side, though it can happen on both. It can be felt on the right or the left, and it can shoot down into the groin or the crease where your leg meets your hip. It often catches you off guard rather than building slowly.
The pain often follows a specific movement: standing up quickly from a chair, rolling over in bed, sneezing, coughing, laughing hard, or getting out of a car. Once you stop moving or shift into a new position, it typically fades after a few seconds to a couple of minutes. This pattern is typical of round ligament pain, but symptoms can overlap with other causes of abdominal or pelvic pain during pregnancy.
The pain typically shows up on its own, without other symptoms like bleeding, fever, or feeling unwell. If bleeding, fever, or feeling unwell comes with the pain, call your provider right away rather than assuming it is just your ligaments stretching. MedlinePlus (NIH) says mild aches and pains that last for short periods during pregnancy are normal, and StatPearls likewise describes round ligament pain as a normal part of pregnancy rather than a sign of disease, while recommending prompt follow-up if pain persists to rule out other causes.

Why It Happens and When It Usually Starts

Two round ligaments run from either side of your uterus, through your groin, and attach near your labia, helping support your uterus as your pregnancy progresses. As your uterus grows and rises up out of your pelvis, these ligaments stretch. StatPearls notes that the round ligaments increase in diameter and length during pregnancy and may cause cramping or pain in the second trimester, sometimes sharp with a pulling sensation. A sudden movement can pull on that already-stretched tissue the way a quick tug pulls on a taut rubber band, which may explain the fast, sharp twinge.

How Long It Lasts Through Pregnancy

MedlinePlus (NIH) says this stretching pain in the lower belly or groin most often happens between weeks 18 and 24. The timing varies from person to person, and some weeks you may barely notice it, while a day of extra walking, a workout, or a bumpy car ride can bring on a cluster of twinges the next.
Symptoms often become less noticeable later in pregnancy, while some people continue to notice occasional discomfort until after delivery. A sudden movement or a long day on your feet can still bring on a jab in the final weeks.
How much you notice it can differ from one pregnancy to the next. If you are unsure whether what you feel is round ligament pain, mention it at your next prenatal visit.

Everyday Moments That Can Set It Off

Getting up from a low chair or the couch, climbing out of bed, and stepping out of a car all ask your body to shift position quickly, which can tug on a stretched ligament. Coughing, sneezing, and laughing can have a similar effect from the inside, possibly because each one tightens your abdominal muscles suddenly.
You can soften the jolt with a simple habit: before you cough, sneeze, or stand up, place a hand or a pillow against your lower belly for light support, then move a little more slowly. Some people also notice more pain after a long car ride or a day of standing at work, possibly because the ligaments are under steady tension. Short breaks to sit, walk, or change position can help.

What Makes It Worse, and What Helps

Beyond those everyday moments, twisting at the waist, prolonged standing, or strenuous activity without warming up first can also leave the area more tender. MedlinePlus (NIH) advises moving slowly or changing positions when you feel the stretching or pain, and says a maternity girdle may help. StatPearls adds warm compresses, bending and flexing at the hips to ease the pulling sensation, gentle daily stretching, and avoiding prolonged standing and heavy lifting. Other simple habits that may help:
  • Move slowly and deliberately, especially when you stand up, sit down, or roll over in bed.
  • Support your belly with your hand or a pillow when changing position.
  • Bend your hips and knees before you stand up rather than lurching upright.
  • Try a maternity support belt or belly band during the day if you are on your feet a lot.
  • Rest on your side with a pillow between your knees.
  • Apply a warm (not hot) compress or take a warm (not hot) bath or shower to ease tight, sore muscles.
  • Ease into gentle stretching or prenatal yoga rather than sudden bursts of activity.
  • Stand tall with your shoulders back and your pelvis level rather than slouching, and wear supportive, low-heeled shoes.
Ask your prenatal provider before taking any pain reliever, since not every over-the-counter option is a good fit during pregnancy. Gentle, paced activity is often part of a healthy pregnancy, and your provider can tell you what suits you; see exercise in the third trimester for what is generally safe to keep doing as your pregnancy progresses.

Round Ligament Pain vs. Contractions and Other Causes of Pain

Several conditions can feel similar, so it helps to know how they differ. A 2023 review of acute abdominal pain in pregnancy notes a tendency to over-diagnose round ligament pain, which can delay the discovery of serious causes such as a ruptured ectopic pregnancy or placental abruption.
Round ligament pain is typically sharp, brief, and tied to a specific movement. A contraction more often feels different: your whole belly tightens into a hard ball, the tightening builds and holds before releasing, and you can often time it from one episode to the next. Contractions do not always hurt, though: ACOG notes that the tightening of preterm labor is often painless. If what you are feeling comes in a repeating pattern instead of fading after a single movement, treat it as a possible contraction and call your provider; see Braxton Hicks vs. real contractions for a closer look at telling the two apart.
If you are earlier in pregnancy and what you feel is more of a mild, crampy ache rather than a sharp one-sided jab, that is a different symptom with its own set of normal and not-normal causes; see is cramping in early pregnancy normal. Severe or persistent one-sided pain early in pregnancy, especially with bleeding, dizziness, fainting, or shoulder pain, needs prompt medical evaluation. ACOG lists sudden, severe pain in the abdomen or pelvis, shoulder pain, and weakness, dizziness, or fainting as symptoms that can develop if a fallopian tube ruptures in an ectopic pregnancy, notes that a rupture can cause life-threatening internal bleeding, and says to go to an emergency room if you have sudden, severe pain, shoulder pain, or weakness. For bleeding or spotting on its own, see spotting during pregnancy: when to worry.
Appendicitis can look different, although the two can overlap. NIDDK (NIH) describes pain that may begin near the belly button and move lower and to the right, sometimes with nausea, vomiting, or fever. That pain can also get worse when you move, cough, or sneeze, so pain that worsens with movement does not by itself tell the two apart, and pain that keeps building instead of easing is a reason to be seen promptly. During pregnancy, a 2026 systematic review on PubMed Central (NIH) notes that the growing uterus can move the appendix sideways and upward, so the pain may be felt higher, in the right flank or right upper quadrant, and not only in the classic lower right position. NIDDK calls appendicitis a medical emergency that requires immediate care.
A urinary tract infection can also cause lower belly discomfort, but it may come with burning or stinging when you urinate, a strong urge to go, or cloudy or strong-smelling urine, which round ligament pain by itself does not typically cause. Urinary tract infections during pregnancy deserve prompt attention; see UTI during pregnancy and why it needs prompt treatment.
Pelvic girdle pain is different: it is often felt toward the back of your pelvis or the pubic bone, may worsen with walking, climbing stairs, or standing on one leg, and usually does not follow the same short, movement-triggered spike. The two can happen in the same pregnancy, so where you feel it and whether it fades quickly or lingers helps tell them apart.
Later in pregnancy, sudden abdominal pain with vaginal bleeding, or a belly that stays stiff, hard, or tender, can be a warning sign of placental abruption and needs urgent evaluation, although a contracting uterus can also feel firm for a short time. Regular or frequent contractions before 37 weeks can be a sign of preterm labor. MedlinePlus (NIH) says heavy bleeding, a stiff and painful belly, or strong and frequent contractions may call for 911, and that any other bleeding late in pregnancy should be reported to your provider right away. ACOG lists regular or frequent contractions or tightening, a change in vaginal discharge or leaking fluid, pelvic or lower abdominal pressure, and a constant, low, dull backache among the signs of preterm labor, and says not to wait: call your ob-gyn right away or go to the hospital. Heavy bleeding, fainting, or a racing heartbeat with abdominal pain can point to serious blood loss and needs emergency care.
In the second half of pregnancy, severe or persistent pain in the upper right belly or under the ribs, especially with a severe headache that does not go away, vision changes, or trouble breathing, also needs urgent evaluation because it can be a sign of preeclampsia. MedlinePlus (NIH) notes that headaches that get worse or do not ease with rest and acetaminophen (Tylenol), especially toward the end of pregnancy, can be a sign of preeclampsia and should be reported to your provider.
If your pain feels different from your usual twinges (more constant, more intense, or paired with any of those other symptoms), call your provider. The MedlinePlus page on aches and pains during pregnancy advises seeing your provider right away for constant, severe abdominal pain, possible contractions, or pain together with bleeding or fever.
Once you have established a usual pattern of baby movements, a noticeable decrease or change in that pattern should prompt a call to your maternity care team right away, whether or not you also have belly pain.

When to Seek Medical Care

When to Seek Urgent or Emergency Care

Typical round ligament pain is uncomfortable but generally considered harmless, and it does not usually indicate a problem with the pregnancy. The patterns below can point to something else going on and call for medical attention rather than home care. The first group needs an ambulance or the emergency room. For the second group, ACOG and MedlinePlus advise calling your ob-gyn right away or going to the hospital. This guidance is in addition to, not a replacement for, the general disclaimer above.

Emergency, call 911 or go to the emergency room immediately if:

  • Sudden, severe pain in your belly or pelvis, shoulder pain, or unusual weakness, especially with dizziness, fainting, or vaginal bleeding early in pregnancy (go to the emergency room or call 911; can be a warning sign of an ectopic pregnancy, including possible rupture)
  • Sudden, sharp abdominal pain with heavy vaginal bleeding or a belly that feels stiff and painful, especially with strong and frequent contractions (call 911 or your local emergency number; can signal placental abruption)
  • Heavy vaginal bleeding, fainting, or a racing heartbeat along with abdominal pain (call 911)
  • Steady, worsening pain that starts near your belly button and moves lower and to the right, or is felt higher on the right side or in the flank, especially with fever, nausea, or vomiting (go to the emergency room; can signal appendicitis or another serious condition)
  • Constant, severe belly pain that does not ease, or pain so intense you cannot stand up straight, walk, or find any position that eases it (go to the emergency room or call 911)
Call your ob-gyn or maternity care team right away, or go to the hospital, if:
  • Regular or frequent contractions or tightening before 37 weeks, leaking fluid, a change in vaginal discharge, pelvic pressure, or a constant, low, dull backache (can signal preterm labor)
  • Vaginal bleeding, or a fever along with belly pain, especially with chills, vomiting, urinary symptoms, or feeling very unwell
  • A noticeable decrease or change in your baby's usual pattern of movement once you have established one, whether or not you also have belly pain
  • A severe headache that does not go away, vision changes, trouble breathing, or pain in the upper right belly or under the ribs, especially in the second half of pregnancy (can be a sign of preeclampsia)

See a doctor soon (same-day or next available appointment) if:

  • Pain that feels different from your usual round ligament twinges: more constant, more intense, or lasting longer than your usual twinges
  • Burning, stinging, or urgency when you urinate
  • Pain that keeps returning and is not relieved by rest or changing position
  • Twinges that are frequent or bothersome enough to disrupt your sleep or daily activities, or that leave you unsure whether they are round ligament pain (mention them at your next available appointment)

Frequently Asked Questions

How long does round ligament pain last, and can it come back in the third trimester?

Round ligament pain often runs from the second trimester into part of the third, and the pattern can come and go as your uterus keeps growing. Many people find it less noticeable as the weeks go on, though some keep feeling occasional twinges until delivery, and a sudden movement or a long day on your feet can still bring on a jab. Pain that feels different from your usual twinges is worth a call to your provider.

When does round ligament pain start in pregnancy?

Most often it starts in the second trimester, but some people notice it a little earlier or later. It is linked to the ligaments that support the uterus stretching as it grows. Severe or persistent one-sided pain early in pregnancy, especially with bleeding, dizziness, fainting, or shoulder pain, needs prompt medical evaluation, and sudden, severe pain needs the emergency room.

Can round ligament pain happen in the first trimester?

Sometimes. MedlinePlus says round ligament pain most often happens between weeks 18 and 24, and a 2023 review describes it as often starting toward the end of the first trimester or the beginning of the second. Pain earlier than that has other possible causes, so tell your provider about any one-sided or persistent pain.

Is round ligament pain a sign of labor?

Not by itself. Round ligament pain is linked to stretched ligaments rather than the uterus contracting. Labor involves regular or frequent tightening across your whole belly that builds in strength and frequency over time, while round ligament pain is typically a brief, sharp jab tied to a specific movement. If you have regular or frequent tightening before 37 weeks, do not wait; call your ob-gyn or go to the hospital right away.

Can round ligament pain happen on both sides at once?

Yes. Round ligament pain can be felt on the right, the left, or both sides, and it can switch sides from one day to the next, sometimes even on the same day, depending on which way you moved or how you were sitting. Sharp pain that keeps getting worse, or comes with bleeding, fever, or dizziness, needs a call to your provider right away.

How is round ligament pain different from a contraction?

Round ligament pain is typically sharp and brief, tied to a specific movement like standing up or rolling over, and fades quickly. A contraction more often feels like your whole belly tightening into a hard ball that builds, holds, and releases, sometimes in a pattern you can time. The two can be hard to tell apart, so if pain comes in a repeating pattern, treat it as a possible contraction and call your provider.

Does round ligament pain mean something is wrong with my baby?

Typically not. StatPearls describes round ligament pain as a normal part of pregnancy rather than a sign of disease, though it can still be uncomfortable and is worth mentioning at a prenatal visit. Pain that comes with bleeding, fever, or a change in your baby's usual movements is different and needs prompt evaluation.

What helps round ligament pain right away?

Pause for a moment, since brief twinges often pass on their own, and change position slowly. StatPearls lists warm compresses and bending and flexing at the hips among the measures that may ease the pulling sensation, and MedlinePlus (NIH) says a maternity girdle may help. Supporting your belly with your hand and resting on your side with a pillow between your knees may also help. Ask your prenatal provider before taking any pain reliever.

How is round ligament pain different from appendicitis pain?

Round ligament pain is typically brief, tied to movement, and eases after a short rest. Appendicitis pain may begin near the belly button, move lower and to the right, and keep building, sometimes with fever, nausea, or vomiting. It can also worsen with movement, and later in pregnancy it may be felt higher on the right side, so the two can overlap. If pain does not let up, keeps getting worse, or comes with these symptoms, seek medical care right away.
