Summary

This study follows 192 women who have been pregnant before to learn why some develop pelvic or lower back pain during pregnancy and after childbirth. Researchers will measure body awareness, stress, anxiety, and inflammation to see how these factors relate to pain and balance. The goal is to find better ways to prevent or treat this common pregnancy problem.
