The central nervous system and lungs are maturing well. Week 34 can bring a strong nesting energy for some parents and pure tiredness for others, both of which are very believable responses this late in pregnancy.
The lungs and central nervous system continue maturing, and the baby is building reserves of body fat for life outside. Movements are still important, even if they feel different because space is tighter.
A playful size comparison for this week is cantaloupe. That cantaloupe-sized baby is getting rounder, heavier, and more prepared each day.
Your bump may feel beautifully full and utterly inconvenient at the same time. Pressure through the pelvis, breathlessness, and a strong need to sit down more often are all common now.
Week 34 often brings pelvic pressure, swollen feet, heartburn, back pain, Braxton Hicks, and poor sleep. Some people also notice increased discharge or stronger bursts of nesting energy.
Keep meals simple, balanced, and regular, especially if heartburn makes appetite awkward. Fluids, fibre, and iron can help you feel less drained and less constipated in these final weeks.
Easy walking, stretching, and movement in water can feel wonderfully supportive at week 34. Pay attention to recovery, because even normal days can be more taxing now.
It is common to swing between wanting the baby here soon and wanting more time to prepare. Late pregnancy often makes both desires feel intense.
Partners can channel nesting in useful ways, like checking bags, organising transport, or prepping meals, while also protecting you from overdoing it physically.
Urgent warning signs this week include heavy bleeding, severe abdominal pain, fever, fainting, leaking fluid, or a severe headache with vision changes. Get checked for reduced movements, bleeding, leaking fluid, regular contractions, or symptoms that feel like preeclampsia such as headache, swelling, and visual changes. From week 28 onward, contact your care team promptly if the baby's usual movements slow down, weaken, or stop.
Yes, late pregnancy can be physically heavy and sleep is often broken. Energy levels commonly dip again in the final stretch.
Pack your hospital bag so it's ready and waiting. Having your bag mostly ready by now often lowers background stress, even if labour is still a few weeks away.
