What are common signs of preterm labor?

Regular contractions are a common and significant sign of preterm labor. In the context of pregnancy, contractions are the tightening and relaxing of the uterine muscles, which can occur as the body prepares for labor. When these contractions happen more frequently than typical Braxton Hicks contractions, especially if they are occurring at intervals of less than 10 minutes or lasting more than 30 seconds, they can indicate that labor is beginning prematurely.

Recognizing these contractions alongside other symptoms—such as pelvic pressure, lower back pain, or changes in vaginal discharge—is crucial for timely intervention and management, which can include hydration, rest, or medications to delay labor if necessary.

In contrast to contractions, increased appetite, sudden cravings, and frequent headaches are not standard signs of preterm labor. Increased appetite and cravings can occur throughout pregnancy, particularly in the second trimester, and are generally not associated with labor signs. Frequent headaches may occur for various reasons unrelated to labor, such as hormonal changes, tension, or dehydration, but they do not specifically signify that labor is approaching.
