Just as you begin to make it out of the nauseating and exhausting haze of the first trimester, it’s common for pregnancy to throw another “fun” new symptom your way. You may experience a sharp pain down your lower belly after an unexpected sneeze, or a dull ache in your groin after getting up too quickly from the couch. Luckily the pain doesn’t stick around for too long, but what exactly is it? There's a solid chance that it's round ligament pain.
If you're wondering "what are round ligament pains?" we've got you. Round ligament pain is very common in pregnancy. In fact, it affects as many as 3 in 10 folks in their second trimester. Not typically tied to an injury, the pain often occurs as your uterus naturally grows up and out of your pelvis.
In this post, we'll dive into everything you need to know about round ligament pain in pregnancy, including flags that your pain may be linked to something more serious. But before we get into the facts, let's start with some quick tips and stretches that can bring you immediate relief.
When you have round ligament discomfort in pregnancy, it can help to slow down and move carefully. Try these tips:
Some gentle stretching of the muscles in your hips, lower abdomen, and inner thighs can ease muscle pain and round ligament irritation. Try these fourstretches below, holding each for at least 30 seconds, and doing 2-3 sets if comfortable.
None of these stretches should cause pain or discomfort. If they do, discontinue to the stretch, and reach out to a pelvic PT for specific recommendations for your symptoms.

The round ligament is a round, rope-like ligament that runs from the top sides of your uterus, forward and down into your pelvis through the broad ligaments, where it anchors in your labia majora. It’s a paired ligament, meaning you have one on each side of your uterus.
The round ligament is mostly fibrous — like you would expect a ligament to be — but it also contains some smooth muscle as it attaches to the uterus. The fibromuscular nature of the round ligament helps it perform its main function, which is to help maintain the position of the uterus.
When not pregnant, the round ligament is strong and flexible, and it mostly functions totally unnoticed in your body.
When you're pregnant, the round ligaments stretch, widen, and lengthen as your uterus grows, helping to keep it in the normal anteverted position (when the uterus tips forward a tad, towards your belly). Hormones including relaxin and progesterone are thought to help relax the smooth muscle and soften the connective tissue, allowing the ligaments to adapt to pregnancy.
As your uterus grows in pregnancy, the top expands up and out of your pelvis around the start of your second trimester. As it grows, the round ligaments grow and lengthen along with it.
Normally, the round ligaments stretch and contract slowly, allowing for small shifts in your pelvic organs, while helping to keep your uterus in place. But during pregnancy, these ligaments can become overstretched, and more easily strained. Quick movements or stressors (like can happen from a forceful cough, or quick shift of your body into standing) can further stretch the ligament, causing it to quickly contract, causing a sharp or cramping pain.
Most commonly, round ligament of uterus pain starts near the end of the first trimester or beginning of the second trimester (around 12-16 weeks). This timing coincides with when your growing uterus begins to expand up and out of your pelvis, putting increased stretch on the round ligaments. However, some women may experience symptoms earlier or later depending on factors like:
Although much less common, another cause of round ligament discomfort in pregnancy is round ligament varices (RLV). Although uncommon, RLV are swollen and dilated veins in the round ligaments that are often mistaken for an inguinal hernia because of the similar symptoms. Increased blood volume and hormone changes in pregnancy can cause swelling at the front of the hips (along the inguinal ligament) and a feeling of fullness.

Round ligament pain is most often felt as a sharp, cramping, or sudden stabbing sensation, in the lower abdomen (on one or both sides). Pain can radiate down the front of the hips and into the groin similar to where your underwear runs (along the path of the round ligament as it travels down to the labia). For some, it can present as a more general, dull ache in the lower belly during pregnancy. For some, it can present as a more general, dull ache in the lower belly during pregnancy.
Round ligament pain is most often provoke by quick movements, like:
Round ligament symptoms can be painful, but usually they are pretty quick, lasting for only a few moments after aggravated.
Round ligament pain itself is typically not dangerous, but it can be uncomfortable. If you’ve never experienced it before, the pain can be alarming. The good news is that symptoms usually ease up by the third trimester and resolve completely after pregnancy, when your uterus shrinks back down to its pre-pregnancy size.
It is important to be able to distinguish round ligament pain from other types of abdominal pain in pregnancy. There are many causes of abdominal pain in pregnancy ranging from benign to serious conditions that need to be evaluated by a healthcare professional ASAP.
Common causes of abdominal pain in pregnancy:
If you experience any new, changed, or persistent abdominal pain in pregnancy, it’s best to be evaluated by a healthcare provider, especially if you also have any of the following symptoms:
If these small adjustments don’t help (and even if they do), it's a good idea to schedule a visit with a pelvic floor physical therapist (PFPT). A specialized PFPT will listen to your pelvic pain symptoms, help rule out other complications, and do a complete assessment of your movement and strength (among other things) to help determine which exercises, body adjustments or stretches may reduce your symptoms.
A PT will also set you up for a more comfortable remainder of your pregnancy. While some discomfort can be expected as your body goes through extensive (and very impressive) amounts of change, you don’t have to "just deal with." There are many things we can do to minimize and even eliminate pain.
Pelvic physical therapy can play a key role in easing the discomfort of round ligament pain during pregnancy by improving posture, movement patterns, and core stability. Through gentle exercises, education, and hands-on techniques, physical therapists can support expectant mothers in navigating the physical challenges of pregnancy.
