Backache is one of the most common pregnancy problems, especially in the later months. The pain usually goes away after the baby is born. But for many women, back pain lingers for months after giving birth. Your expanding uterus shifts your center of gravity and stretches out and weakens your abdominal muscles.

This is why your back may feel worse at the end of the day.
