Signs of Labor at 37 Weeks: What to Expect and When to Call Your Doctor
By week 37 of pregnancy, your baby could make their arrival any time. It’s normal to feel more tuned in to changes in your body as you look for signs of labor at 37 weeks. The most common early labor signs include regular, increasingly strong contractions, water breaking (amniotic fluid leaking or gushing), and loss of the mucus plug. There are also other subtle shifts in your body you may notice as labor approaches.
It’s important to remember that signs of labor aren’t exactly the same for everyone. There is no one-size-fits-all timing or checklist. Feeling unsure about what’s normal or when to contact your doctor is completely natural—many people wonder which changes really mean labor is near. Below, you’ll find guidance to help make things clearer.
What does labor at 37 weeks mean?
At 37 weeks pregnant, your baby is considered early term—their major organs are developed, and they’re getting ready for life outside the womb. Your hormones are shifting noticeably now, setting the stage for labor to start at any time.
The most frequent signs of labor at 37 weeks include:
- Regular, strengthening uterine contractions
- Loss of the mucus plug (often a stretchy, pinkish discharge)
- Leaking or sudden gush of amniotic fluid (water breaking)
- Your belly dropping lower as the baby settles into your pelvis, often making breathing feel easier
What’s a “real” contraction?
Braxton Hicks (also called “practice contractions”) often start weeks before labor. These are irregular, generally mild, and commonly stop with rest. In contrast, true labor contractions:
- Become regular (every 10, then 7–8, then 5–6 minutes apart)
- Last longer and feel stronger over time
- May start in the lower back and radiate around to the front
Resting or changing position doesn’t make these contractions go away.
What to Watch For at 37 Weeks – Real-Life Examples
🤰 Example 1: You have mild cramps in the morning, and they fade away as the day goes on—this is likely just Braxton Hicks, which improve with rest.
🤱 Example 2: You notice regular, increasingly intense contractions every few minutes that continue into the night—this is a strong sign that real labor has begun.
💧 Example 3: You suddenly feel a rush or steady leak of clear or straw-colored fluid—this means your water has broken, and it’s important to seek care right away.
🩹 Example 4: You see mucus on your underwear that’s sticky and pinkish or blood-tinged—losing your mucus plug can be an early sign of labor, but birth could still be days away.
What’s Happening in Your Body as Labor Begins?
As the end of pregnancy approaches, your body produces more oxytocin, a hormone that triggers uterine contractions. Your cervix gradually softens and shortens (“ripens”), and your baby drops lower into your pelvis. The mucus plug, which sealed and protected the cervix, is released, marking the start of the body’s preparations for labor.
The classic sign of labor is your water breaking (rupture of membranes), but for some, this doesn’t happen until much later during labor. Sometimes, leakage is slow or barely noticeable—no matter what, let your healthcare provider know if you think your waters may have broken.
Risks and When to Be Extra Cautious
While 37 weeks is considered early term, there are certain situations that require extra attention:
- Severe pain or contractions that start suddenly and intensely, especially with heavy bleeding, abdominal tenderness, or dizziness—these need immediate medical assessment.
- High fever or chills, especially if your water has broken—this may signal infection.
- Unusual or foul-smelling discharge, which could also indicate infection and needs urgent evaluation.
- Significantly decreased baby movements. Always check in with your provider if you notice your baby moving much less than usual.
When to Call Your Doctor or Head to the Hospital
- Regular, stronger contractions about 5–10 minutes apart
- Your water breaks (leaking or gushing amniotic fluid) or you notice any bleeding
- Unusual or severe lower abdominal pain, or a sudden feeling of being unwell
- Difficulty breathing, dizziness, or feeling faint
- Marked decrease or absence of baby movements
If any of these happen, don’t delay—get medical advice or care promptly.
