Short answer

Sharp pelvic girdle pain (PGP) and lower back pressure are very common during the third trimester as your body prepares for birth. These symptoms often stem from the combination of shifting hormones, a changing center of gravity, and increased stress on the pelvic joints. Relaxin Hormone: This hormone loosens ligaments in the pelvis to prepare for delivery, which can lead to joint instability and "shooting" pains.

Summary

Sharp pelvic girdle pain (PGP) and lower back pressure are very common during the third trimester as your body prepares for birth. These symptoms often stem from the combination of shifting hormones, a changing center of gravity, and increased stress on the pelvic joints.

Most likely causes

  • Relaxin Hormone: This hormone loosens ligaments in the pelvis to prepare for delivery, which can lead to joint instability and "shooting" pains.
  • Symphysis Pubis Dysfunction (SPD): Misalignment or excessive movement of the pubic symphysis joint.
  • Shifted Center of Gravity: As the baby grows, your lower back arches more (lordosis), putting intense pressure on the lumbar spine and sacroiliac (SI) joints.
  • Baby’s Position: The baby descending into the pelvis can increase direct pressure on the pelvic floor and nerves.
