Round ligament pain

6-minute read

Contact your doctor or midwife if you notice bleeding from your vagina at any time during your pregnancy. If you have heavy vaginal bleeding, strong pain or feel very unwell, call triple zero (000) immediately and ask for an ambulance.

Key facts

  • You have 2 round ligaments, 1 on each side of your uterus; these help hold your uterus in place.
  • As your uterus gets bigger during pregnancy, your round ligaments grow and can spasm, causing pain in your lower abdomen or groin — this is called round ligament pain.
  • Symptoms of round ligament pain last for a few minutes or a few hours, and can include sudden sharp pains, cramping or a pulling sensation.
  • Round ligament pain is not dangerous for you or for your baby.
  • If you have abdominal pain along with other symptoms, such as bleeding, vaginal discharge, fever, contractions, feel lightheaded or have difficulty standing up, seek medical care immediately.

What is the round ligament?

Ligaments are cord-like pieces of connective tissue. You have 2 round ligaments that are 10 to 12 centimetres long each. Each round ligament is attached to either side of your uterus, and help to hold your uterus in place. They also connect the front part of your uterus to your groin.

What happens to the round ligament during pregnancy?

When you are pregnant, hormones make your round ligaments looser and more elastic. They become longer and thicker. Your round ligaments help to support your changing body and stretching uterus as your baby grows.

While you are more likely to feel these symptoms on your right side, you may also feel round ligament pain on your left side or on both sides. Your pain can last for a few minutes or for a few hours.

Round ligament pain is most often felt during the second trimester. Some people have round ligament pain from earlier on in pregnancy.

Round ligament pain is common and normal to experience during pregnancy.

What causes round ligament pain?

As your baby grows, your round ligaments stretch and get longer to support your growing uterus. This sometimes makes them spasm (twitch), triggering round ligament pain.

Some things trigger round ligament pain, including:

Round ligament pain is different to pelvic girdle pain (also known as symphysis pubis dysfunction). Both types of pain happen because of changes to your body during pregnancy. Round ligament pain develops when your round ligaments spasm from being stretched and growing. Pelvic girdle pain happens when your pelvic ligament has relaxed making your pelvis joint move more.

While you feel round ligament pain in your lower abdomen near your hips and groin, pelvic girdle pain causes discomfort and pain in your pelvis and lower back area. You might also feel pelvic girdle pain into your upper thighs and perineum.

Will I still have round ligament pain after having my baby?
