Round Ligament Pain at 36 Weeks Pregnant

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.

👶 What's Happening at Week 36

Your baby is now the size of a swiss chard.

  • The baby sheds most of the lanugo (fine body hair).
  • Fat continues rounding out the cheeks and body.
  • The digestive system is ready to process breast milk.

🔬 Why You're Experiencing Round Ligament Pain at Week 36

  • 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

💊 Relief Tips for Week 36

1
Move SlowlyAnticipate movements — slow down when changing positions, getting up, or turning over.
2
Flex Your Hips Before CoughingBending at the hips when you know you're about to cough, sneeze, or laugh can prevent the sudden jolt that triggers pain.
3
Warm CompressA warm heating pad on the affected area for 15 minutes can ease ligament spasm.
4
Prenatal Support BeltA belly support band reduces ligament strain by distributing the weight of the growing uterus.
5
Gentle StretchingHip flexor stretches and prenatal yoga can relieve tension in the round ligament.

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.
