As the uterus grows during pregnancy, the round ligament stretches, commonly causing pain.


  1. The pain can be from the strain on the ligaments as the pelvis widens, the ligaments spasm, or by the ligaments pulling on nearby sensitive structures.
  2. It can feel like pelvic pain or back pain and can be a sharp pain, a dull ache or a tugging sensation. The pain is more often experienced on the right side.
