37 weeks pregnant.
Officially early term. Your baby is fully developed and could arrive any day — though most stay put until week 39–41.

What may be changing in your body
Bag-of-bricks tired but increasingly nesting. Watch for labor signs: regular contractions, water breaking, or a bloody show.
Early labour signs to know
From this week your baby is considered early term. Learn the trio: regular strengthening contractions, waters breaking, and a bloody show. Any of them means calling your maternity unit for advice.
Nesting surge
A burst of energy and urge to organise is common right before labour for many people. Use it lightly — you want reserves for the main event.
Increased pelvic and back pressure
The baby's head grinding into position makes sitting and walking uncomfortable. A birth ball, warm baths, and frequent position changes are the daily toolkit.
Cervical changes you can feel
Twinges, pressure, and period-like aches reflect the cervix softening and thinning. These can simmer for days or weeks before labour proper begins.
Loose bowels
Hormones that prepare the uterus can loosen the bowels a day or two before labour in some people. Stay hydrated and treat it as a possible heads-up rather than a guarantee.
Movements to keep watching
Your baby has less room but movements should stay just as frequent and strong right up to and during labour. Any reduction means contacting your maternity unit immediately — full-term is exactly when this vigilance matters most.
Your week 37 checklist
- Review the signs of labour with your birth partner so you both know the plan for each scenario.
- Keep your phone charged and maternity notes with you whenever you leave the house.
- Prepare padsicles or cold packs and arrange the postpartum recovery station at home.
- Rest deliberately — bank sleep in deposits, because labour does not schedule itself.
for partners this week
For partners this week
You are on call now: keep your phone loud, your fuel tank above half, and alcohol minimal. Re-read her birth preferences one more time and memorise the three signals that mean phoning the unit — regular contractions, waters breaking, bleeding — plus the non-negotiable one: reduced movements means calling immediately.
Ideas from Elara partner mode for week 37
- One flower, again. The home stretch. Remind her she's a woman to you — not just a belly.
- Stock snacks for the hospital. Nuts, chocolate, water. You'll be there too.
What comes next
Labor can start anytime. Look out for regular contractions less than 5 minutes apart, water breaking, or bright red bleeding.
Common questions
How do I know labor is starting for real?
True labour announces itself with contractions that become regular, longer, stronger, and closer together over time — they persist whatever you do, unlike practice tightenings that fade with rest or a bath. Waters breaking or a bloody show can come before, during, or after contractions begin. When contractions demand your full attention and follow a pattern, or your waters go, call your maternity unit and let them guide the timing.
What is the difference between a bloody show and bleeding?
A show is mucus streaked with pink or brownish blood — the plug from the cervix coming away as it opens — and is a normal pre-labour sign worth mentioning to your midwife. Fresh, flowing red blood like a period is not a show and needs an immediate call to your maternity unit, whatever the hour. When in doubt about which you are seeing, call and describe it; that is always the right move.
Is 37 weeks fully full term?
At 37 weeks your baby is classed as early term — mature enough that labour would not be stopped, and most 37-week babies do very well. Full term technically runs from 39 to 40 weeks, and evidence shows those extra weeks still add valuable brain and lung maturation. So it is a milestone to celebrate, not a target to hurry past; labour will not be induced this early without a medical reason.
How many months is 37 weeks pregnant?
37 weeks is usually counted as the ninth month of pregnancy and trimester 3. Months do not divide evenly into weeks, so clinicians date pregnancy in weeks and days; the weeks-to-months converter shows the full table.
