Round ligament pain, often described as sharp groin twinges, is most common in the second trimester. However, it's still possible to experience these sensations as you move through your third trimester, though typically with less intensity and frequency.
Why it shows up this trimester
By the third trimester, your uterus has grown significantly, and the round ligaments that support it are already quite stretched. While they've adapted to the increased size, sudden movements can still cause them to stretch rapidly, leading to those familiar brief, sharp sensations. Think of it as the ligaments having less 'give' left, so any quick change in position, like rolling over in bed, standing up too fast, or a sudden cough, can still momentarily pull on them. The sheer weight and size of your baby can also contribute to the general pressure on your pelvic area, making the ligaments more sensitive.
What it tends to feel like now
In the third trimester, round ligament pain still presents as a quick, sharp, stabbing, or pulling sensation in your lower abdomen or groin, usually on one side. It's typically very brief, lasting only a few seconds, and then subsides. It doesn't usually come with a tightening of the uterus like a contraction, nor does it typically radiate to your back or intensify over time. If you're feeling persistent pain, cramping, or anything that feels rhythmic, it's always a good idea to check in with your care provider.
