34 Weeks Pregnant

Baby’s Development

Fetus ~45 cm (small cantaloupe), weight ~2,100 g (4.7 lb) [1]. Vernix (white, waxy protective coating) thickens. Lungs nearly mature. Fingernails reach past fingertips — may scratch face in utero. Body fat ~15% of body. Skin: smooth, pink. Brain: still developing rapidly. Movement: strong but space tight. Survival rate: 98%+ [2].

Pregnancy Symptoms

Third trimester. Symptoms: backache, heartburn, constipation, leg cramps, swelling, headaches, Braxton Hicks (more frequent, more intense). Uterus ~14 cm above navel. Kicks strong, possibly less frequent. Round ligament pain, sciatica, pelvic pressure (intensifying). Heartburn, shortness of breath, frequent urination. Restless legs, hemorrhoids, carpal tunnel. Sleep very difficult. Fatigue. Anxiety about labor common. Practice “labor signs” education [2].

Body Changes

Uterus ~14 cm above navel, ~1/2 way between navel and sternum. Weight gain: 26-34 lbs by week 34 typical. Bump large. Stretch marks, linea nigra, melasma, visible veins, varicose veins. Breasts 2+ cup sizes up, colostrum may leak. Possible “pregnancy mask” (melasma). Swelling in feet/ankles. Heart rate 80-100 bpm. Center of gravity shifted [2].

Tips for Week 34

• Begin perineal massage (optional) — 5 min daily. Vitamin E, almond, or coconut oil. Reduces perineal tearing at birth. Start gently; 34-36 wk typical.
• Address sleep — pregnancy pillow, side-sleeping, cool room, consistent bedtime, no screens 1 hr before, magnesium glycinate, Unisom (with provider OK). If anxiety, talk to OB.
• Address anxiety about labor — talk to provider, attend class, hire doula, read evidence-based birth stories, visualize the day.
• Address pelvic pressure — Kegels, side-sleeping, support belt, pelvic tilts, prenatal PT, avoid standing for long periods.

Things To Do (Checklist)

• Begin perineal massage (5 min daily)
• Optimize sleep (pillow, position, magnesium)
• Address labor anxiety (class, doula, provider)
• Address pelvic pressure (Kegels, PT, support belt)
• Continue kick counting (10 in 2 hrs daily)
• Preeclampsia watch; fetal position

Frequently Asked Questions

Q: Will my baby be early? A: Full term = 37-42 weeks. Average first baby: 40 wk 5 days. Late preterm (34-36 wk): most do well but may need NICU briefly. Talk to OB about your specific risk [1].

Q: I’m having trouble sleeping. Help? A: Common. Pregnancy pillow, side-sleeping (left preferred), cool room, consistent bedtime, no screens, magnesium glycinate (with provider OK), Unisom. If anxiety, talk to OB [2].

Q: I have hemorrhoids. Will they go away? A: Often yes, but slowly. Weeks to months post-birth. Fiber, water, sitz baths, witch hazel, topical creams (with provider OK). Surgery rare [1].

For Dads

• Be the “go-bag” keeper — packed and by the door. Comfortable clothes, phone charger, snacks, change of clothes, toiletries, going-home outfit for baby, car seat installed.
• Drive the hospital route — at different times of day. Day entrance vs. night entrance. Parking. Where to check in. Backup driver.
• Practice counter-pressure techniques — hip squeezes, lower back pressure, sacral pressure. YouTube “counter pressure for labor.” Doula or class can teach.
• Read The Expectant Father Ch. 32 — third trimester, your role in labor.
• Pray for sustained growth and protection — final weeks are about weight gain and brain development.
