Why does pelvic pain occur?

Pelvic pain in pregnancy can be caused for a number of reasons including:

  • the additional pressure on the pelvis due to the growing baby,
  • ligaments softening due to the hormonal changes, or
  • changes to your posture.

With all these changes occurring, the pelvis become less stable and can begin to move unevenly. Inflammation can occur, which in turn, will lead to discomfort, pain or even mobility issues.
