Signs of Labour: How to Tell If It’s Starting or Still Not Time Yet
If you’re currently in your third trimester and find yourself Googling “Is this a contraction or just gas?” at 3 AM, welcome to the club. We’ve all been there. You’ve read the books, but when your stomach actually tightens, your brain suddenly goes blank.
Is it time to grab the hospital bag, or should you just drink a glass of water and lie down? Identifying labour signs can be incredibly tricky because early symptoms often mimic general late-pregnancy discomfort.
In this guide, we are moving past the vague “trust your gut” advice. Instead, we’re looking at the biological markers, the 5-1-1 rule, and the specific symptoms that differentiate a “false alarm” from the real deal.
The Confusion of Early Labour: Why It’s So Hard to Tell
Early labour (the latent phase) is the longest part of the process. For many women, it doesn’t start with a dramatic “movie-style” water breaking. It starts quietly.
Biologically, your cervix is beginning to soften, thin out (efface), and open (dilate). This process causes physical sensations that are nearly identical to:
• Period-like cramps: Dull aching in the lower abdomen.
• Lower back pain: A persistent ache that doesn’t go away when you shift positions.
• Digestive upset: Your body’s way of “clearing out” to make room for the baby.

Signs of Labour That Usually Mean “Not Time Yet”
It is common to experience “prodromal labour” or “false labour.” These are real physical sensations, but they aren’t yet causing the cervical changes needed for birth.
Irregular Contractions (Braxton Hicks)
The biggest differentiator here is consistency. Braxton Hicks are “practice” contractions.
• The Test: Drink a large glass of water and lie on your left side. If the tightenings slow down or stop, it’s not active labour.
• The Pattern: They are irregular. One might be 10 minutes apart, the next 20, then 5. True labour signs involve a tightening that gets progressively closer together.
The Infamous Mucus Plug
Losing your mucus plug (the “bloody show”) is a sign that your cervix is changing, but it is not a sign that labour is imminent. Some women lose their plug two weeks before they actually give birth. Unless it is accompanied by regular contractions, you likely still have time.
Sudden Nesting Energy
If you suddenly feel the urge to deep-clean your baseboards with a toothbrush, you’re nesting. While this often happens in the final days of pregnancy, it’s a hormonal surge, not a physiological guarantee that contractions are starting in the next hour.
When It’s Actually Starting: The “Something is Happening” Phase
Once you move past the “maybe” stage, your symptoms will become more “rhythmic.” This is where you need to start paying attention to your labour sign patterns.
The “Back Labour” Ache
Unlike standard pregnancy back pain (which usually comes from carrying extra weight), labour-related back pain feels like a deep, internal throb that radiates toward your pelvis. If this ache starts to come in waves—getting stronger then fading—your baby might be positioning themselves for the exit.
Digestive Clearing (Diarrhea and Nausea)
According to the Mayo Clinic, many women experience loose stools right before labour begins. Your body releases prostaglandins which soften the cervix but also stimulate the bowels. If you’re feeling “flu-ish” without a fever, your body might be prepping for the big event.
The Gold Standard: The 5-1-1 Rule
If you want to avoid being sent home from the hospital for “arriving too early,” you need to follow the 5-1-1 rule. This is the medical standard for identifying active labour.
The 5-1-1 Rule Defined:
5: Contractions are consistently 5 minutes apart (measured from the start of one to the start of the next).
1: Each contraction lasts for at least 1 full minute.
1: This pattern has continued for 1 hour straight.
When you hit the 5-1-1 mark, it’s time to call your doctor or midwife. This is when the “work” of labour is officially underway. If you want to know exactly what happens next, read my breakdown on What Actually Happens During Labour (From 1cm to Baby Out).
Signs It Is DEFINITELY Time: Active Labour
You’ll know you’ve moved from “early” to “active” labour when your focus shifts entirely.
The “No-Talk” Zone
In early labour, you can usually talk through a contraction. In active labour, you will likely need to stop mid-sentence, lean on a table, and breathe through the intensity. If you find you can no longer hold a conversation during the tightening, your body is moving into the serious phase.
Increased Pelvic Pressure
This feels like the baby is physically “dropping” or pushing against your rectum. This heaviness is a major labour signthat the baby is moving into the birth canal.
Emergency Signs: Go to the Hospital Immediately
Regardless of your contraction pattern, there are a few “Red Light” signs that mean you should head to the hospital right now:
• Your Water Breaks: Whether it’s a gush or a trickle, once the amniotic sac ruptures, the risk of infection increases. Note the color—it should be clear. If it is green or brown, head in immediately.
• Bright Red Bleeding: This is different from the “bloody show” (which is pinkish/brownish mucus). Bright red blood requires immediate medical assessment.
• Decreased Fetal Movement: If you notice your baby isn’t kicking as much as usual, don’t wait for contractions. Go in for a check-up.
• Urge to Push: If you feel an uncontrollable urge to bear down, your baby is likely very close!

How to Manage the Wait (Without Going Crazy)
The days leading up to birth are a mental game. You’re tired, you’re sore, and you’re over being pregnant.
• Rest: If you can sleep, sleep. You’ll need the energy for active labour.
• Hydrate: Dehydration can actually cause “false” contractions that hurt but don’t do any work.
• Stay Distracted: Watch a movie, bake something (if you have the energy), or read up on Safe Sleep for Baby to get your nursery ready.
Final Summary Checklist
• False Labour: Stops with movement, irregular, no “bloody show,” manageable pain.
• True Labour: Follows the 5-1-1 rule, gets stronger with movement, persistent back pain, can’t talk through it.
Labour is a marathon, not a sprint. If you’re ever in doubt, call your healthcare provider. It’s better to have a “false alarm” visit than to be stressed at home!
Sincerely,
