Preterm labor is defined as labor that begins before 37 weeks of pregnancy. It involves regular uterine contractions that cause the cervix to thin or open earlier than expected. Not every episode of early contractions leads to an early delivery, but preterm labor always deserves prompt evaluation because babies born too early can face serious health challenges.
According to the American College of Obstetricians and Gynecologists (ACOG), babies born before 37 weeks may have difficulty with breathing, feeding, temperature regulation, and long-term development. The earlier a baby arrives, the greater the potential risks. That is why recognizing the signs of preterm labor early and getting timely care can make a real difference for both mom and baby.
Why Full-Term Delivery Is Important
A full-term pregnancy gives a baby critical time to grow, especially when it comes to lung and brain development. When preterm labor is caught early, providers may be able to recommend treatments that slow contractions, support fetal lung maturity, or help plan a delivery at a facility equipped for early arrivals.
Many women who experience early contractions go on to deliver at full term. But the safest approach is always to take symptoms seriously and get checked rather than assume everything is fine.
Warning Signs You Should Not Ignore
Preterm labor does not always show up in obvious ways. Some women describe it as mild cramping or a sense of pressure that just feels different from their usual pregnancy discomfort. If something feels off before 37 weeks, it is always better to call your provider than to wait.
