As a pregnancy advances, the mother’s pelvis begins to tip backwards to balance the forward weight of the developing fetus with expansion of the uterus. The backward movement of the pubic and tailbones increases the arch in the lower back. These changes can put stress on the spine, enhancing its natural S shape, and can also strain other muscles and ligaments.
