I’m 39 Weeks Pregnant. Is Labor About to Start?

Understanding the Signs That Your Baby Is Nearly Ready—and How to Recognize the Difference Between Preparation and True Labor

Key Takeaways:

✓ At 39 weeks, your baby is considered full term, and labor may begin at any time, although there is no reliable way to predict the exact day.

✓ Your body may begin showing signs that it is preparing for labor, including stronger Braxton Hicks contractions, increased pelvic pressure, and changes in your cervix.

✓ Most of the physical changes you notice during the final days of pregnancy are normal and do not necessarily mean labor has begun.

✓ True labor contractions become stronger, longer, and closer together over time, while false labor usually improves with rest or a change in activity.

✓ Even though these final days may feel endless, every hour brings you closer to meeting your baby.

Introduction

By the time you reach thirty-nine weeks of pregnancy, one question begins to dominate almost every conversation.

“Do you think the baby will come today?”

Family members ask.

Friends send text messages.

Neighbors smile knowingly when they see you walking.

Even complete strangers at the grocery store seem eager to predict when your baby will arrive.

After months of counting weeks, attending prenatal appointments, and preparing your home, your due date suddenly feels incredibly close. Every unfamiliar sensation makes you wonder whether this is finally the beginning of labor.

Was that contraction different?

Why does my pelvis suddenly feel so heavy?

Did my baby just drop lower?

Should I call my doctor?

Should I go to the hospital?

As an obstetrician, I found that thirty-nine weeks was one of the most exciting—and sometimes most emotionally challenging—times in pregnancy. Mothers were eager to meet their babies, yet they often felt caught between anticipation and uncertainty. Every day seemed filled with hope that today might finally be the day.

The encouraging news is that, at thirty-nine weeks, your baby has reached an important milestone. Pregnancy is now considered full term, meaning your baby’s lungs, brain, and other organs have matured remarkably well for life outside the womb. Although babies continue making subtle developmental progress even during these final days, most are beautifully prepared for birth whenever labor naturally begins.

That does not mean labor follows a predictable schedule.

One of the greatest misconceptions about pregnancy is that labor begins exactly on the due date. In reality, your due date is an estimate rather than an appointment. Some healthy mothers deliver before forty weeks, while others remain pregnant for several days afterward. Both situations are usually completely normal in uncomplicated pregnancies.

The challenge is that your body begins preparing for labor long before labor actually starts.

During these final weeks, your cervix gradually softens. Your baby often settles deeper into your pelvis. Hormonal changes continue preparing the uterus for increasingly effective contractions. You may notice stronger Braxton Hicks contractions than you experienced earlier in pregnancy. Pelvic pressure may increase as your baby’s head moves lower, making walking feel slower and causing frequent trips to the bathroom because of added pressure on your bladder.

Each of these changes can make you wonder whether labor has finally arrived.

Sometimes they are signs that labor is approaching.

Sometimes they simply reflect the remarkable preparation taking place inside your body.

That uncertainty can be frustrating.

Many mothers wake each morning wondering if this will be the day they finally hold their baby. They organize the nursery one more time, double-check the hospital bag, and keep their phone within easy reach wherever they go. Every small cramp, tightening, or backache captures their attention.

Emotionally, these final days can feel surprisingly complex. You may be thrilled to meet your baby while also feeling nervous about labor. You may be physically uncomfortable yet reluctant for pregnancy to end because these are the last quiet moments you and your baby will share together. You may find yourself alternating between incredible patience and complete impatience—all within the same afternoon.

Those emotions are completely understandable.

You are standing at the threshold of one of life’s greatest transitions.

Fortunately, your body usually provides clues that help distinguish ordinary late-pregnancy discomfort from true labor. Understanding those differences can replace much of the uncertainty with confidence. Rather than wondering whether every contraction means it is time to rush to the hospital, you can recognize the normal signs of preparation while knowing what changes truly signal that your baby’s birthday is finally beginning.

The waiting may feel difficult, but it has a purpose. Every day that passes has helped prepare both you and your baby for the remarkable journey of childbirth. Before long, the wondering will be over, the contractions will become unmistakable, and the moment you have imagined for months will finally arrive.

How Will I Know When Labor Has Really Started?

One of the most reassuring things I could tell my patients was this: when true labor begins, it usually becomes increasingly difficult to mistake it for anything else. Although every woman’s labor is unique, true labor follows a recognizable pattern that helps distinguish it from the normal aches and pains of late pregnancy.

During the final weeks before delivery, many women experience Braxton Hicks contractions, often called “practice contractions.” These tightenings can be surprisingly strong, especially during the evening or after a busy day. Your abdomen may become firm for thirty seconds to a minute before gradually relaxing again. While they can certainly be uncomfortable, Braxton Hicks contractions are preparing your uterus for labor rather than causing your cervix to open significantly.

One of the easiest ways to recognize Braxton Hicks contractions is that they are inconsistent. They may occur every ten minutes for a while, then disappear completely. Changing your position, drinking water, taking a warm shower, or simply resting often causes them to become less frequent or stop altogether. They may return later in the day or the following evening, but they do not develop the steady rhythm that characterizes true labor.

True labor behaves very differently.

Real labor contractions gradually become stronger, longer, and closer together. Instead of fading away with rest, they continue despite walking, changing positions, or trying to relax. At first, they may feel like menstrual cramps or a dull ache across your lower abdomen and back. As labor progresses, the contractions become more intense and more predictable. You begin noticing that each one lasts a little longer than the last, and the time between contractions steadily shortens.

Many women are surprised to discover that labor is usually a gradual process rather than a sudden event. Television often portrays labor beginning with an immediate rush to the hospital, but most first-time mothers experience hours of early labor before active labor develops. This gradual progression allows your cervix to soften, thin, and slowly dilate while your baby continues descending through the birth canal.

Another common question involves the so-called “bloody show.” As your cervix begins preparing for labor, you may notice a small amount of pink, brown, or blood-tinged mucus. This occurs as the mucus plug that has sealed the cervix throughout pregnancy begins to loosen. Seeing this discharge can be exciting because it often means your body is making progress toward labor. However, it is important to remember that labor may begin within hours, or it may still be several days away. The bloody show is a sign that your body is preparing, not a guarantee that delivery is imminent.

Some women wonder whether they will know if their water has broken. In movies, this often appears as a dramatic gush of fluid. In real life, it can happen that way, but many women experience only a slow trickle or intermittent leaking of clear fluid. If you think your membranes have ruptured, it is important to contact your healthcare provider for guidance, even if contractions have not yet begun. Your provider will advise you on the next steps based on your pregnancy and the amount and appearance of the fluid.

As an obstetrician, I often encouraged expectant mothers not to focus on finding a single dramatic sign of labor. Instead, pay attention to the overall pattern. Is the discomfort becoming stronger? Are the contractions becoming more regular? Are they continuing despite rest? Looking at the whole picture usually provides much more helpful information than trying to interpret one isolated symptom.

During these final days, patience can be surprisingly difficult. You may wake every morning wondering whether today will be your baby’s birthday, only to go to bed that night still pregnant. Friends and family continue calling for updates, and every telephone conversation seems to end with the same question: “Any news yet?” It is understandable if you begin feeling impatient or discouraged.

Remember that your baby is not late simply because labor has not started today. Every healthy day your baby remains safely in the uterus allows continued maturation and preparation for life outside the womb. Your body and your baby are following an intricate biological process that has been unfolding since the day pregnancy began. Labor usually starts when both are ready.

Very soon, the waiting will end. The contractions will become unmistakable, your healthcare team will guide you through each stage of labor, and the months of anticipation will give way to an unforgettable first cry. The discomforts, questions, and uncertainty of the third trimester will suddenly fade into the background as you experience one of life’s greatest privileges—meeting the child you have carried, protected, and loved long before you ever saw that precious face.
