Round Ligament Pain
Round ligament pain is one of the most common second-trimester complaints. It causes sharp, stabbing or pulling pain in the lower abdomen or groin that is triggered by sudden movements.
Common Causes
- Two thick ligaments support the uterus from each side — as the uterus grows rapidly in the second trimester, these ligaments stretch
- Sudden movement (rolling over, standing up quickly, laughing, coughing, sneezing) causes the ligament to spasm
- Ligament softening from relaxin hormone increases susceptibility to strain
Remedies That May Help
Move Slowly
Anticipate movements — slow down when changing positions, getting up, or turning over.
Flex Your Hips Before Coughing
Bending at the hips when you know you're about to cough, sneeze, or laugh can prevent the sudden jolt that triggers pain.
Warm Compress
A warm heating pad on the affected area for 15 minutes can ease ligament spasm.
Prenatal Support Belt
A belly support band reduces ligament strain by distributing the weight of the growing uterus.
Gentle Stretching
Hip flexor stretches and prenatal yoga can relieve tension in the round ligament.
Rest
If active, rest until the pain subsides — it typically passes within seconds to minutes.
When to Call Your Doctor
- Pain is severe, persistent, or does not resolve within a few minutes
- Pain is accompanied by fever or chills
- Pain is on one side and feels different from usual round ligament pain
- You have bleeding with the pain
- Pain is accompanied by burning with urination (possible UTI)
- Pain continues beyond 30 minutes
Frequently Asked Questions
When does round ligament pain start?
It most commonly begins in the second trimester, around weeks 14–20, when uterine growth accelerates.
What does round ligament pain feel like?
It is typically described as a sharp, stabbing, or pulling sensation in the lower abdomen, sides, groin, or inner thighs. It lasts a few seconds to a minute.
Can round ligament pain hurt on both sides?
Yes — there are two round ligaments (one on each side), so pain can occur on either or both sides.
Is round ligament pain a sign of miscarriage?
No — round ligament pain is a normal, benign symptom of pregnancy. Miscarriage pain is typically more severe, prolonged, and accompanied by bleeding.
Does round ligament pain go away after birth?
Yes — once the baby is born and the uterus returns to its normal size, round ligament pain resolves completely.
