32 Weeks Pregnant

Baby’s Development

Your baby has grown to about 42 centimeters long — roughly the size of a honeydew melon or a jicama — and weighs approximately 1,700 grams, or about 3.7 pounds [1]. Your baby’s skin is becoming smoother as fat fills in the wrinkles that characterized the earlier weeks. The lungs are more mature now, with surfactant production increasing and breathing motions growing stronger. Inside the brain, trillions of connections are forming. Body fat now makes up about 10 to 12 percent of your baby’s weight, and most babies have settled into the cephalic (head-down) position by this point. The fingernails have reached the fingertips, and the toenails have reached the toe tips. The fine lanugo hair that covered your baby’s body is beginning to shed, while the protective vernix coating remains thick [2].

Body Changes

Your uterus is now about 12 centimeters above your navel, and a weight gain of 24 to 32 pounds by this point is typical. Your bump is large, and you may notice stretch marks, the linea nigra, melasma, more visible veins, and varicose veins. Your breasts may have grown by two or more cup sizes, and colostrum may leak occasionally. The “pregnancy mask” (melasma) can appear on your face, and swelling in your feet and ankles is common. Your heart rate may range from 80 to 100 beats per minute, and your center of gravity has shifted forward [2].

Tips for Week 32

• Address back pain with prenatal physical therapy, massage, a support belt, side-sleeping with a pillow between your knees, and warm baths. Gentle core work targeting the transverse abdominis can also provide relief.
• Begin perineal massage (this is optional) — spending about 5 minutes daily starting around week 34. Using vitamin E, almond, or coconut oil, this gentle practice can help reduce the risk of tearing during birth.
• Address your fears about labor by talking to your provider, attending a class, hiring a doula, and reading evidence-based birth stories from authors like Emily Oster or Ina May Gaskin. Knowledge and preparation go a long way toward easing fear.
• Stay hydrated and eat enough fiber — aim for 80 to 100 ounces of water and 25 to 30 grams of fiber per day, which can help reduce constipation, swelling, urinary tract infections, and hemorrhoids.

Things To Do (Checklist)

• Address back pain with PT, massage, or a support belt
• Begin perineal massage starting at week 34
• Address labor fears through a class, doula, or your provider
• Continue prioritizing hydration and fiber
• Continue kick counting (aim for 10 movements in 2 hours daily)
• Preeclampsia watch; fetal position check

Frequently Asked Questions

Q: Can I deliver vaginally if my baby is breech? A: Most OBs recommend a C-section for a breech baby at term, as it is generally safer for the baby. Some very experienced providers do offer vaginal breech delivery, and an ECV at 36 to 37 weeks can sometimes turn the baby before labor begins [1].

Q: I’m worried about tearing. How can I prevent it? A: Perineal massage starting at 34 weeks, a warm compress during pushing, controlled pushing (rather than coached Valsalva), water birth (which has some supportive evidence), and avoiding episiotomy unless medically needed can all help. Discuss your preferences with your provider ahead of time [2].

Q: Should I get the RSV vaccine? A: The Abrysvo RSV vaccine is recommended between 32 and 36 weeks (typically September through January) so that antibodies can pass to your baby. This protects your newborn during their first six months, when they are most vulnerable. Talk to your OB about whether it is right for you [1].
