10 Early Signs of Labor: How to Tell It's Close

Your due date is close, and suddenly every twinge feels like a signal. Is this the real thing, or another false alarm?

A first pregnancy leaves you with plenty of questions, and reading your own body is the hardest part. Some early signs of labor show up weeks ahead; others mean your baby is coming within a day or two.

Here is what each sign actually means, how to tell a practice contraction from the real thing, and when a symptom is your cue to call your provider.

Early Signs of Labor

The nine months of pregnancy can sometimes feel like a decade. The first trimester often brings morning sickness. The second may feel like a breeze, but then the third hits, and you might feel like you are back to square one.

Some of those discomforts in the last month signify something big is happening. Your baby and body are preparing for the special day.

Here are 10 early signs you may already feel:

1. Baby Drops Lower

All women carry their babies differently. Some have a high, protruding belly, while others carry low. If you are like me, you reach full growth capacity around six months and spend the last three hearing “any day now, huh?”

However, as your due date closes in, your baby should turn head-down. This usually happens before 32 weeks. Your baby then begins a slow descent into the pelvis.

This “dropping” is technically called “lightening,” and it often brings relief. The baby might have put pressure on your lungs and stomach for months. As your little one lowers, your breathing may improve and heartburn might decrease. For a first baby, lightening can happen anywhere from a few weeks to a few hours before labor, so it signals progress rather than an exact countdown ⁽¹⁾.

However, the “waddle” usually kicks in now. When your baby drops into the pelvis, it becomes almost impossible to walk normally. Comfortable shoes are a definite advantage at this time; ditch the heels.

You may also feel the need to urinate more frequently. Think about the extra pressure your bladder is under as your little one rests on it ⁽²⁾.

2. Nesting Instinct Kicks In

As you close in on the finish line, pregnancy fatigue often turns into a burst of energy.

“Nesting” is very real. It can make pregnant women go full power with cleaning, organizing, and prepping for the baby. Where did the energy come from? It is likely the extra adrenaline your body produces during the final weeks.

Resist the urge to overdo it. Now is the prime time to rest up for labor ⁽³⁾.

Conversely, you might feel totally exhausted. Feeling drained and having bouts of crying are common.

Listen to your body. Take naps, enjoy warm baths, or find other ways to pamper yourself. Ask a family member for help or let your partner tackle the to-do list.

3. Weight Gain Stops

We typically gain weight throughout pregnancy. It is natural and unavoidable. Some women gain a lot, while others gain just a little.

However, as you venture toward the end of the final trimester, the scale might stabilize. You might stop gaining weight as you reach “full capacity.”

Some women even lose a few pounds. Do not worry if you see the numbers drop. Just because you are losing weight does not mean the baby is shrinking.

Your peanut is still gaining as they should. If you lose more than a few pounds or feel concerned, talk to your health care provider.

Here is what contributes to weight stabilization:

• Amniotic fluid decreases: The amniotic fluid levels naturally drop slightly toward the end of pregnancy.
• Frequent urination: As your baby presses on your bladder, you expel more fluid.
• Activity levels: If you are in nesting mode, you burn extra calories preparing for the baby ⁽⁴⁾.

4. Discomfort Increases

Between waddling to the bathroom and trying to nap, you might experience general discomfort.

Your belly feels like it might burst, and your back is aching. You may also experience more cramping.

As the due date comes into sight, the discomfort can interfere with sleep. Here are a few tricks to help:

• Sleep on your left side: This increases blood flow to your uterus and helps nutrients reach your baby.
• Keep knees bent: Position a pillow between your knees to support your hips and spine.
• Support belly and back: Place a maternity pillow under your bump to relieve pressure ⁽⁵⁾.

If heartburn is keeping you awake, try these tips:

• Drink cold milk: Try a small glass right before bed.
• Prop your head up: Raising your upper body with a couple of pillows can keep acid reflux from creeping up at night.

5. Cervix Dilates and Effaces

During the last month of pregnancy, the cervix transforms. Your uterus is preparing to squeeze a full-grown baby out through a small opening. Two primary changes happen: dilation and effacement.

Dilation means “opening.” This can be a slow process or happen quickly. Some women dilate slowly over the last few weeks, while others do not dilate until active labor begins. Do not panic if you are still “closed” at your checkup ⁽⁶⁾.

Doctors measure dilation in centimeters. Once the cervix dilates regularly, you are usually in active labor. For most full-term babies, the cervix is fully dilated at 10 centimeters (about the size of a bagel).

Effacement means “thinning.” As the cervix dilates, it softens and thins to make room for the baby. This is measured in percentages ⁽⁷⁾. The cervix starts thick and thins out until it is like a sheet of paper.

Your OB may conduct cervical exams during the last weeks. These checks can be uncomfortable, but they help track progress.

6. Contractions Feel Real

Some women have “false” labor pains, known as Braxton Hicks, during pregnancy.

These pains do not feel false when you are having them. Even if you escaped them earlier, they often appear in the final weeks.

Braxton Hicks are irregular and do not mean labor is starting. Real contractions settle into a steady rhythm, each lasting closer to 60 seconds, and keep getting stronger no matter what you do.

Here is how to tell the difference:

• Location of pain: Braxton Hicks often feel like a tightening of the abdomen. Real labor often starts in the back and wraps around to the front.
• Consistency: Time your contractions. If they are irregular, they are likely Braxton Hicks. If they are regular and get closer together, you may be in the first stages of labor.
• Movement response: Change your position or walk around. If the pain stops, it is likely false labor.
• Intensity progression: Real contractions get stronger and longer over time. Braxton Hicks usually stay the same intensity ⁽⁸⁾.

7. Diarrhea Happens

It is not glamorous, but as labor approaches, you may experience the “runs.”

The same hormones that soften your cervix and start contractions also stimulate your bowels, so loose stools can mean labor is close, often within 24 to 48 hours. The muscles in your uterus, rectum, and the rest of your body relax together, which is nature’s way of clearing room for the baby’s passage.

If it becomes frequent, tell your provider. Otherwise, drink plenty of water to replace lost fluids.

To manage pre-labor diarrhea:

• Watch your diet: Avoid fatty, fried, or spicy foods that irritate the gut.
• Check vitamins: Some prenatal vitamins upset the stomach; taking them with a meal might help.

Though typically harmless, watch for dehydration signs:

• Decreased urine production or dark urine.
• Dry or sticky mouth.
• Dizziness or lightheadedness.
• Severe headache.

Dehydration is dangerous for you and the baby, so treat it quickly ⁽⁹⁾.

8. Mucus Plug Falls Out

The notorious mucus plug blocks the cervical opening to protect the baby from bacteria.

How and when the plug comes out varies. Some women see a large gelatinous blob, while others notice bits and pieces. It typically looks like egg whites or snot.

Losing the plug means your cervix is ripening. It can happen days or weeks before labor. If you lose it early in the third trimester, it may even grow back.

If you notice pink, brown, or red streaks in the mucus, this is called “the bloody show.” This usually indicates labor is imminent (within a few days or hours). Pack that hospital bag now ⁽¹⁰⁾.

9. Water Breaks

In movies, water breaks in a public place with a giant splash, and the baby arrives five minutes later. Reality is usually different.

Water breaking is often one of the final signs. It actually starts labor for only about 10 to 15 percent of women; more often it happens once active labor is well underway, or a doctor breaks it manually in the hospital. When it does break on its own, labor usually follows within 24 hours.

If your water does break at home, here is what it might feel like:

• A gush: A noticeable splash of fluid.
• A trickle: A slow, constant leak down your leg that you cannot hold back with Kegel muscles.
• A pop: Some women feel a sensation like a balloon popping inside ⁽¹¹⁾.

Note the color and smell, because it tells your provider a lot. Normal amniotic fluid is clear or pale yellow and odorless. Call right away if the fluid looks green or brown, which can mean the baby has passed meconium, or smells foul, which can signal an infection, and tell your provider what time it broke ⁽¹²⁾.

10. Joints Feel Loose

You might feel a bit wobblier than usual. During pregnancy, your body produces a hormone called relaxin.

As the name suggests, it relaxes everything. Its job is to loosen up the ligaments in your pelvis to allow the baby to pass through the birth canal. Unfortunately, it loosens ligaments all over your body.

You might feel disjointed or clumsy. This is another reason for the famous “pregnancy waddle.” Be careful on stairs and slippery surfaces during these final weeks.

Early Labor FAQs

When Can I Expect the Signs to Appear?

Early signs of labor follow two timelines. The gradual ones, dropping, nesting, and extra discomfort, can start anytime in the third trimester and usually become obvious about a month before labor. The late signs, loose stools, losing the mucus plug, and the bloody show, tend to show up in the final week to few hours before birth.

When Should I Contact My Doctor or Midwife?

Call your provider right away if your water breaks, you have bright red bleeding, or your baby is moving noticeably less. For contractions, use the 5-1-1 rule: call once they are 5 minutes apart, last 1 minute each, and have held that pattern for 1 full hour ⁽¹³⁾.

How Long Can Early Labor Last?

Early labor usually lasts 6 to 12 hours for a first baby, though it is unpredictable and can stretch across a couple of days when contractions start and stop (prodromal labor). It tends to be much shorter for second and later births ⁽¹⁴⁾.

Can I Help My Labor Along Naturally?

A few natural methods may give a full-term labor a gentle nudge, though none is guaranteed. Sex supplies prostaglandins that soften the cervix, walking and staying upright use gravity to help the baby descend, and nipple stimulation releases oxytocin to spark contractions. Clear any of them with your doctor first ⁽¹⁵⁾.

Do Babies Get More Active Before Labor?

There is no fixed pattern before labor. Some babies grow quieter as they run out of room, while others stay active right to the end, so a change in activity by itself is not a reliable labor sign. What matters is this: never ignore a clear drop in movement. If your baby is not moving as usual, contact your provider immediately.

What Triggers Labor to Start?

Labor is triggered by a mix of hormonal and physical signals rather than one switch. Researchers believe that once the baby’s lungs mature, they release a protein that cues the mother’s body to produce prostaglandins and oxytocin, the hormones that ripen the cervix and start contractions ⁽¹⁶⁾.

Can Labor Start Without Losing a Mucus Plug or Water Breaking?

Yes. Labor often begins with regular contractions alone, with no dramatic mucus plug or water-breaking moment first. The plug can slip out unnoticed while you are on the toilet, and for many women the water does not break until active labor or even the pushing stage.

Is Labor More Likely to Start at Night?

Labor does seem to start at night for many women. Melatonin, the hormone that rises in the dark, appears to work alongside oxytocin to help contractions build, and there may be an evolutionary pull toward laboring when the surroundings are dark, quiet, and safe ⁽¹⁷⁾.

Could You Be in Labor and Not Know It?

Yes, especially in the earliest stage of labor. With a high pain tolerance, the first contractions can feel like a dull backache or mild period cramps that are easy to brush off. You are unlikely to miss active labor, though, once contractions turn intense, regular, and impossible to talk through.

I recommend that moms distract themselves from beginning labor pains. Before labor starts, choose an early labor project. Many moms choose to watch a movie, finish a craft project, or bake cookies. Time your contractions occasionally so you have an idea of how close they are becoming. If you fixate only on the contractions, it can make labor seem longer!

The Last Push

The last month of pregnancy can feel endless, and every cramp brings the same question: “Is this it?” That swing between excitement and nerves is completely normal.

Watch for the signs above, start timing your contractions once they turn regular, and keep your provider’s number and your hospital bag within reach. Your body and your baby are sorting out the timing together, so rest while you can and trust that the day is coming.
