What is a common sign of impending labor?

A common sign of impending labor includes backache and increased urinary frequency. As a woman approaches labor, hormonal changes can lead to contractions that may cause discomfort in the lower back. Additionally, as the fetus descends into the pelvis, pressure on the bladder can result in more frequent urination. These symptoms indicate that the body is preparing for the labor process.

In contrast, loss of appetite may occur in some women during late pregnancy but is not a reliable sign of impending labor. Fullness in the abdomen can represent various stages of pregnancy, and increased energy levels—often referred to as the "nesting instinct"—may occur, but this can vary significantly between individuals and is not universally indicative of labor approaching. Thus, the combination of backache and urinary frequency offers a more direct correlation with the onset of labor.
