What may be changing in your body

Bump is heavy. Some experience light-headedness from blood pressure dips. Practice contractions become more frequent.

Light-headedness on standing

Blood pressure dips and blood pooling in the legs can cause head rushes when you stand quickly. Rise in stages and sit back down at the first sign of dizziness.

Stronger practice contractions

Braxton Hicks can now feel firm enough to make you pause. They should still be irregular and settle with rest — time them if unsure, and call your maternity unit about any regular pattern before 37 weeks.

Pelvic floor heaviness

A bearing-down heaviness after time on your feet reflects the baby's weight on the pelvic floor. Keep up daily pelvic floor exercises and take genuine off-your-feet breaks.

Blurry moments and tired eyes

Fluid changes can make vision briefly soft, especially with contact lenses. Persistent blurring, flashing lights, or spots need a same-day call to your midwife or doctor.

Leaking with laughter

The pelvic floor is under maximum load now. Pads help in the short term; the exercises help for good.

Difficulty finding any comfortable position

Sitting, standing, and lying all have a time limit now. Rotating positions hourly, plus a birth ball for sitting, keeps discomfort spread rather than concentrated.

Your week 34 checklist

  • Start perineal massage a few times a week if you plan to try it — from now is the evidence-based window.
  • Agree the exact plan for older children and pets when labour starts, including a backup person.
  • Pre-register or complete any hospital admission paperwork your unit allows in advance.
  • Sit on a birth ball daily — it encourages good baby positioning and eases pelvic pressure.

A useful partner move this week

Agree your labour logistics out loud this week: who you each call first, the childcare or pet plan, and what you grab on the way out of the door. Then rehearse it once, genuinely — a five-minute walkthrough now prevents the headless-chicken version later.

What comes next

Babies born at 34 weeks usually do well with brief NICU support. Term begins at 37.

Common questions

What does it mean when the baby drops or engages?

Engagement means the baby's head settles down into the pelvis ready for birth — you may notice easier breathing but heavier pelvic pressure and more bathroom trips. First babies often engage from around 34 to 38 weeks, while subsequent babies may not drop until labour begins. Engagement is not a countdown timer: it can happen weeks before labour or hours before.

When should I go to the hospital with contractions?

General guidance for a first baby is to call your maternity unit when contractions are regular and roughly every five minutes, lasting about a minute, for at least an hour — but call earlier if your waters break, you see bleeding, the baby's movements reduce, or you simply feel something is wrong. Every unit prefers a phone call first so they can advise based on your situation. Trust the instruction you are given over any app or formula.

What happens if my baby is still breech — what is an ECV?

If your baby remains breech around week 36, you will usually be offered an external cephalic version (ECV) — an obstetrician uses firm hand pressure on your bump to encourage the baby to somersault head-down, with monitoring before and after. It succeeds roughly half the time and is considered safe in the right candidates. If it does not work or is not suitable, your team will talk through a planned caesarean or, in some cases, a vaginal breech birth.

How many months is 34 weeks pregnant?

Pregnancy months do not divide evenly into weeks, so clinicians date pregnancy in weeks. At 34 weeks, you are in trimester three.
