Week 34 of Pregnancy
At 34 weeks pregnant, you're in the final stretch of the third trimester. Your baby is growing rapidly and preparing for life outside the womb, while your body is working overtime to support these final developmental milestones. You may feel more tired, more breathless, and notice stronger Braxton Hicks contractions. It’s a good time to check off any remaining to-dos and prioritize rest and comfort as you near the finish line.
Baby’s Size
Your baby is about the size of a canary melon.
Baby’s Development at 34 weeks
Fat Accumulation Increases
Your baby is now gaining about half a pound per week, adding fat that helps regulate body temperature after birth. This fat also fills out their cheeks, giving their face a more baby-like appearance.
Lung Development Progresses
Although not fully mature, your baby’s lungs are producing surfactant, a substance that helps keep the air sacs in the lungs open for breathing after birth.
Sleep Patterns Begin Forming
Your baby is starting to develop sleep-wake cycles and may even enter REM (dream) sleep, showing signs of brain activity and personality.
Responsive to Stimuli
Baby can now respond more noticeably to light, sound, and touch, especially your voice, which may have a soothing effect from the outside.
Pregnancy Symptoms during Week 34
-
Your uterus has grown higher into your ribcage, making it more difficult for your lungs to fully expand. Shallow breathing may be more noticeable, especially when lying down.
-
Increased fluid retention and pressure on blood vessels can lead to more swelling in your lower body by day’s end.
-
Finding a comfortable position continues to be a challenge. Kicks, cramps, and frequent waking may interrupt your rest.
-
As your baby drops lower into the pelvis, there's greater pressure on your bladder, making bathroom trips more frequent.
-
You may experience more noticeable, irregular tightening sensations as your uterus “practices” for labor.
Pregnancy checklist at 34 weeks pregnant
-
Start researching and calling pediatricians to find one that aligns with your values and location. Some offices offer prenatal interviews or consultations.
-
If you plan to breastfeed, now is a good time to familiarize yourself with positions and latch techniques. Download ChildbirthU’s Breastfeeding Support Guide for evidence-based information and visuals.
-
Confirm who will be your primary support person during labor and who will help post-birth. Talk openly about expectations and responsibilities.
-
Wash baby’s onesies, blankets, and crib sheets in a gentle, fragrance-free detergent to remove any residue or irritants.
-
Between nesting urges and last-minute prep, don’t forget to slow down. Short naps, feet elevation, and light stretching can ease discomfort and restore energy.
34 Weeks Pregnant Belly
By week 34, your belly is likely round, prominent, and very noticeable, often sitting high as your baby continues to grow rapidly. However, some people may begin to notice their belly starting to drop lower as the baby begins engaging in the pelvis, preparing for birth. This shift can bring a mix of sensations, from relief in the upper abdomen to increased pressure and heaviness lower down.
The added weight of your growing bump can significantly impact your posture and balance, making it more challenging to maintain your usual activities without feeling fatigued. You might notice yourself leaning back more to compensate for the forward pull, which can put extra strain on your lower back and hips, sometimes leading to discomfort or aches.
To help manage these physical changes, wearing a supportive belly band or maternity support belt can provide gentle compression and help redistribute the weight more evenly across your body. Additionally, focusing on maintaining good posture, by keeping your shoulders back and your spine aligned, can reduce unnecessary strain and help you feel more comfortable throughout the day.
Taking breaks to rest and doing gentle stretching or prenatal yoga can also improve circulation and alleviate muscle tension. Listening to your body and adjusting your movements accordingly will support your well-being as you prepare for the final weeks of pregnancy.
