34 Weeks Pregnant
At 34 weeks pregnant your baby is about 18 inches long and close to 5 pounds — roughly the size of a butternut squash — and most babies have settled into a head-down position. The waxy vernix on your baby's skin is thickening, fat is still filling out, and swelling in your ankles and fingers is one of the most common things you'll notice this week.

How big is your baby at 34 weeks?
Your baby is about 18 inches long now, head to heel, and weighs somewhere around 5 pounds — roughly the size of a butternut squash. The waxy white coating called vernix is getting thicker on the skin to protect it from the amniotic fluid and help with the journey through the birth canal. Underneath that vernix, fat is still being laid down, which is part of why babies often look a little less wrinkled in late ultrasounds than they did at 28 or 30 weeks. The fine downy hair called lanugo, which has covered your baby for months, is starting to shed and may be partly swallowed, then passed in the first dark, sticky bowel movement after birth.
Most babies have settled into a head-down (vertex) position by this point, which is what most providers will be hoping to see. If your provider tells you your baby is still breech or transverse, try not to panic — there is still time for many babies to turn on their own, and your provider can talk you through options like an external cephalic version a bit later if needed. Your baby's hearing is sharp this week. They recognize your voice, your partner's voice, and many of the everyday sounds around your home, and a steady heartbeat from your chest is one of the most calming things they know. Movement may feel different now — less sharp jab, more roll, stretch, and shove against your ribs as space gets tight.
Keeping track of how often your baby moves is one of the most useful things you can do for the next several weeks. Most providers recommend picking a quiet time of day, lying on your side, and noticing how long it takes to feel 10 distinct movements — kicks, rolls, and jabs all count. Many parents feel 10 movements well within an hour. The key thing to watch for is a clear change from your baby's usual pattern. If movement feels noticeably less or different than the day before, do not wait it out at home — call your provider's office or labor and delivery line so they can listen in.
34 weeks pregnant symptoms
Your uterus now reaches well up under your ribs, and your fundal height — the distance from your pubic bone to the top of your uterus — is roughly 34 centimeters. These are the common, normal things you may notice this week:
- Mild swelling (edema) — puffy ankles by the end of the day, rings that feel tight, slightly fuller cheeks, shoes that no longer slip on the way they used to
- Heartburn that often peaks now as the uterus pushes on your stomach; propping up with extra pillows can help
- Hip and pelvic aches, round-ligament pulls, and leg cramps, sometimes at 2 a.m.
- Braxton Hicks contractions — irregular, painless tightenings, especially after a busy day or when you haven't drunk enough water
- Frequent bathroom trips and harder-to-find comfort at night
- Nesting energy — a sudden urge to wash baby clothes or scrub the kitchen at 11 p.m.
Swelling is driven by your blood volume being nearly 50 percent higher than before pregnancy and your uterus pressing on the large veins that return blood from your legs. It is normal and not dangerous on its own — but sudden swelling in your face and hands, or one leg much more than the other, is worth a same-day call. A big glass of water and 20 minutes lying on your left side will usually settle practice contractions; real labor contractions get stronger, longer, and closer together.
Taking care of yourself this week
This is a great week to be intentional about pelvic floor work. Gentle daily Kegels — squeeze, lift, hold a few seconds, then fully relax — help with bladder control now and recovery later. Just as important is learning to release: a pelvic floor that cannot relax can make pushing in labor harder. Around week 34, many providers also recommend starting perineal massage a few times a week, which research suggests may reduce the chance of tearing during a first vaginal birth. Your provider, midwife, or a pelvic floor physical therapist can show you how. Gentle hip circles on a birth ball, side-lying stretches, and a daily walk also keep your hips mobile and may help your baby settle low.
- Fiber and water do real work against late-pregnancy constipation — vegetables, fruit (especially berries, pears, and prunes), whole grains, beans, and lentils.
- Iron-rich foods like lean red meat, poultry, eggs, beans, and dark leafy greens support the higher blood volume your body carries; pair them with vitamin C foods like citrus or peppers to improve absorption.
- Small, steady snacks work better than large meals, which press uncomfortably on your stomach this late.
- Start a postpartum freezer stash — even a few bags of soup, chili, and cooked grains will feel like a small miracle in the first weeks home.
Standard pregnancy food safety still applies: wash produce thoroughly, and avoid unpasteurized dairy, deli meats unless steaming hot, raw sprouts, and high-mercury fish like swordfish and king mackerel. This is also a good time to finalize who will be at the birth, share your hospital preferences with your support person, and start packing the hospital bag if you haven't yet — future-you will be glad it's ready by 36 weeks, just in case.
Appointments & tests
Most US practices see you every two weeks at this point, then shift to weekly visits beginning around week 36. A standard visit this week will include checking your blood pressure, dipping your urine for protein and sugar, weighing you, measuring fundal height with a tape measure, and listening to your baby's heartbeat with a handheld Doppler. Your provider may also feel your belly to estimate your baby's position — head-down, breech, or transverse. If your baby is not yet head-down, many still turn before 36 weeks, and your provider can talk you through options.
This is a good week to start more focused conversations about your birth plan. Talk through what matters most to you: who you want present at the birth, your hopes around movement and positions during labor, your preferences around pain management (from no medication to nitrous oxide to an epidural), and your wishes for the first hour with your baby — skin-to-skin contact, delayed cord clamping, and feeding choices. A birth plan is a starting point for a conversation, not a contract. A few practical things to ask about: when to pre-register at the hospital (most ask you to do it by 36 weeks), what number to call when you think you are in labor, and what Group B strep screening will look like in the next couple of weeks.
Call your provider if
- A clear decrease in your baby's movements compared to their usual pattern
- Any bright red vaginal bleeding heavier than a smear on toilet paper
- A sudden gush or steady trickle of fluid from your vagina (your water may have broken)
- Regular contractions getting closer together more than three weeks before your due date (possible preterm labor)
- Severe or persistent headache, sudden swelling in your face or hands, vision changes, or upper-right belly pain (possible preeclampsia)
- Heavy bleeding soaking a pad in an hour, fainting, or no movement at all after lying on your left side for an hour — go to the ER or call 911
