Introduction
Welcome to the 34th week of your pregnancy! As you approach the final weeks of your third trimester, your body and your baby are undergoing significant changes in preparation for labor and delivery. This comprehensive guide will walk you through your baby's development, common symptoms you may experience, and essential steps to take as you prepare for your little one's arrival.
Baby Development at 34 Weeks
Size and Weight
At 34 weeks, your baby is approximately the size of a cantaloupe, measuring about 17.84 inches (45.3 cm) from head to toe and weighing around 5.24 pounds (2.37 kg) 12.
Organ and Sensory Development
Your baby's organs and senses continue to mature:
- The ears are nearly fully formed, and your baby can respond to sounds, light, and touch 3.
- The digestive system is preparing for the transition to breast milk or formula after birth 4.
Physical Appearance
Your baby is becoming rounder and chubbier as they accumulate fat layers beneath the skin. The fingernails have grown to the tips of the fingers, and the toenails will reach the tips of the toes by week 38 5.

Common Pregnancy Symptoms at 34 Weeks
Aches and Pains
Pelvic and Lower Back Pain
The growing weight of your baby puts extra pressure on your joints, leading to pelvic, lower back, and leg pain. Hormonal changes also contribute to joint relaxation and weakening 4.
Round Ligament Pain
As your uterus grows, the round ligaments that support it stretch, causing brief, sharp pains or dull aches in your lower belly or groin 4.
Sciatica
The weight of your uterus and baby can press on the sciatic nerve, causing a sharp, shooting pain from your buttocks down the back of your leg 4.
Constipation
Increased progesterone levels during pregnancy relax the muscles of your digestive tract, slowing down digestion and leading to constipation. Staying hydrated, maintaining an active lifestyle, and increasing fiber intake can help alleviate this symptom 4.
Braxton Hicks Contractions
These irregular "practice contractions" may become more noticeable and intense during the third trimester. While not typically painful, they can be more prominent when you're dehydrated or overtired. Rest, hydration, and changing positions can help ease the discomfort 4.
Fatigue
As your body works hard to support your growing baby, fatigue is a common complaint during late pregnancy. Trouble sleeping, frequent bathroom trips, and physical strain contribute to this exhaustion 4.
Vaginal Discharge
Changes in vaginal discharge are normal during pregnancy. Leukorrhea, a thin or thick, milky-white or clear discharge with a mild odor, is common. Brown discharge, caused by the presence of old blood, is also normal. However, any green, foul-smelling, or itchy discharge should be reported to your healthcare provider, as it may indicate an infection 4.
Leaking Breasts
Some pregnant women experience leaking breasts during the last weeks of pregnancy. This is caused by hormonal changes regulating milk production and is a sign that your body is preparing to feed your baby. The leaking fluid is colostrum, a highly nutritious substance that will be your baby's first food 4.
Preparing for Labor and Delivery
Monitoring Baby's Size and Position
Your healthcare provider will measure your fundal height at every visit to estimate your baby's size. In high-risk pregnancies, ultrasound may be used instead 4.
Coping with Late Pregnancy Discomforts
As you approach the end of your pregnancy, it's normal to feel tired or bored of being pregnant. Acknowledge your feelings and focus on self-care and preparing for your baby's arrival 4.
Planning for Maternity Leave
If you're working, now is the time to finalize the details of your maternity leave. Communicate with your employer, complete necessary paperwork, and create a transition plan 4.
Considering a Postpartum Doula
A postpartum doula can provide invaluable support during the first days or weeks after birth. They offer care, advice, and practical assistance with household tasks and caring for older children 4.
Practicing Perineal Massage
Perineal massage, performed twice a week during the last several weeks of pregnancy, can help soften and stretch the muscles of the pelvic floor in preparation for vaginal birth. This practice may decrease the risk of tearing, scarring, and the need for stitches, as well as reduce postpartum pelvic pain and incontinence 4.
When to Contact Your Healthcare Provider
Signs of Preterm Labor
Call your healthcare provider if you experience any of the following signs of preterm labor 4:
- Regular, persistent contractions
- Lower back pain that suddenly worsens
- Vaginal bleeding or increased discharge
- Pelvic pressure or cramping
Preeclampsia Warning Signs
Be aware of the warning signs of preeclampsia, a serious blood pressure disorder that most often appears after 37 weeks but can occur earlier. Contact your healthcare provider if you notice 4:
- Swelling in your face or around your eyes
- Excessive swelling in your hands, feet, or ankles
- Rapid weight gain (more than 4-5 pounds in a week)
Self-Care and Comfort Measures
Managing Aches and Pains
Engage in gentle exercises like prenatal yoga, swimming, or walking to help alleviate joint pain and discomfort. Use a support belt or pregnancy pillow for added comfort, and apply heat or cold therapy as needed 4.
Relieving Constipation
Stay hydrated, maintain an active lifestyle, and increase your intake of fiber-rich foods to promote regular bowel movements. Over-the-counter stool softeners may also be used under the guidance of your healthcare provider 4.
Coping with Braxton Hicks Contractions
Rest, stay hydrated, and change positions frequently to help ease the discomfort of Braxton Hicks contractions. If the contractions become regular or painful, contact your healthcare provider 4.
Dealing with Fatigue
Prioritize rest and sleep whenever possible. Maintain a consistent sleep schedule, create a relaxing bedtime routine, and consider using a pregnancy pillow for added comfort. If fatigue is severe or persistent, discuss it with your healthcare provider 4.
Addressing Skin Changes
Pregnancy acne and other skin changes are common due to hormonal fluctuations. Avoid using retinoids, hydroquinone, and certain oral medications during pregnancy. Consult your healthcare provider for safe treatment options, and inform your esthetician of your pregnancy if you opt for a facial 4.
Conclusion
As you navigate the 34th week of your pregnancy, remember to prioritize self-care, stay informed about your baby's development, and don't hesitate to reach out to your healthcare provider with any concerns. By preparing for labor and delivery, managing common pregnancy symptoms, and focusing on your well-being, you'll be better equipped to embrace the final weeks of your pregnancy and welcome your little one into the world.
