What are the signs of preterm labor?

The signs of preterm labor primarily include regular contractions, lower back pain, and fluid leakage. Regular contractions that occur more than four times in an hour can indicate that the body is preparing for labor, even if it is earlier than the expected delivery date. Lower back pain, particularly if it is persistent and not simply achiness, can also be a significant sign, especially if it feels different from the normal discomfort often associated with pregnancy. Fluid leakage may signify the rupture of membranes (water breaking), which is a critical indication that labor may be imminent. Recognizing these symptoms promptly is essential for proper medical intervention to potentially delay labor and improve outcomes for the newborn.

The other options listed do not represent typical signs of preterm labor. Increased fetal movement, nausea, and fatigue might be common during normal pregnancy but do not specifically indicate labor. Similarly, painful urination, heartburn, and leg cramps, while uncomfortable, are more associated with the various physiological changes during pregnancy. Frequent headaches, dizziness, and swollen ankles can occur due to changes in blood volume, pressure, or hydration status, but they are not direct indicators of preterm labor. Understanding the correct signs of preterm labor is crucial for timely medical attention and intervention.
