What is a common symptom of preterm labor?

Lower back pain is a common symptom of preterm labor. This type of pain typically manifests as a dull ache or persistent discomfort in the lower back. It can be different from the typical back pain experienced during pregnancy, as it often comes and goes in a rhythm that can coincide with uterine contractions. The presence of lower back pain in conjunction with other signs such as abdominal cramping, pelvic pressure, or changes in vaginal discharge can indicate the onset of preterm labor and warrants further evaluation by a healthcare provider.

While headaches, frequent urination, and gastrointestinal upset can occur during pregnancy, they are not typically associated with preterm labor specifically. Headaches can be related to hormonal changes or tension but are not a defining symptom of labor onset. Frequent urination is commonly experienced due to the growing uterus's pressure on the bladder but does not indicate labor. Gastrointestinal upset can stem from various causes such as hormonal fluctuations or dietary changes and is not a recognized symptom of preterm labor. Recognizing lower back pain—especially when it's rhythmic or accompanied by other labor signs—is crucial for timely intervention.
