What are the common signs of labor?

The common signs of labor are best represented by regular contractions, bloody show, and rupture of membranes. Regular contractions are a hallmark of labor, indicating that the uterus is actively contracting, which leads to progressive cervical dilation and effacement. These contractions typically become more intense, frequent, and painful as labor progresses.

The term "bloody show" refers to the discharge of mucus mixed with blood that may occur as the cervix begins to dilate and efface, serving as an indicator that labor is approaching. This discharge signifies that the body is getting ready for delivery.

Rupture of membranes, often referred to as "water breaking," involves the amniotic sac bursting, resulting in amniotic fluid leaking. This event frequently suggests that labor is imminent or has already begun, especially if accompanied by contractions.

The other options do not encompass signs that are typically associated with the onset of labor. Spotting and cramping might occur, but they are not definitive indicators of labor. Increased appetite and energy are generally not associated with labor, as women often experience a decrease in appetite and energy levels due to discomfort and the body's focus on preparing for delivery. Fatigue and nesting behavior may occur close to the onset of labor, but they are not clear signs
