The third trimester of pregnancy is an exciting yet challenging time for expecting mothers. As the final stage of pregnancy, it typically spans from weeks 28 to 40. During this period, both physical and emotional changes occur as the body prepares for childbirth. In this article, we will explore what to expect during the third trimester of pregnancy, including the changes in the body, the developing baby, and practical preparations for labor and delivery.
Physical Changes in the Mother
Weight Gain and Body Changes
Throughout the third trimester, weight gain continues as the baby grows. Most women gain about 1 pound (0.45 kg) per week during this period. This weight gain can lead to noticeable changes in the mother’s body. The belly expands significantly, and stretch marks may appear as the skin stretches to accommodate the growing baby.
Hormonal Changes:
Hormonal fluctuations remain prevalent during the third trimester. Increased levels of relaxin, estrogen, and progesterone prepare the body for labor. These hormones can also cause various physical symptoms, including fatigue, headaches, and changes in skin pigmentation.
Breast Changes
Breast development continues in preparation for breastfeeding. The breasts may become larger and more sensitive. Many women notice darkening of the areolas and the appearance of small bumps on the surface of the areolas, known as Montgomery glands, which help lubricate the nipples.
Swelling
Edema, or swelling, is common during the third trimester. Many women experience swelling in the feet, ankles, and hands due to increased fluid retention and pressure from the growing uterus. Elevating the feet and avoiding standing for long periods can help manage swelling.
Digestive Changes
As the baby grows, it can push against the mother’s stomach and intestines, leading to heartburn, indigestion, and constipation. Eating smaller, more frequent meals and avoiding spicy or fatty foods can alleviate some of these discomforts.
Emotional Changes
Mood Swings
Emotional changes are common during the third trimester. Hormonal fluctuations, combined with the anticipation of childbirth, can lead to mood swings. Expecting mothers may feel excitement, anxiety, or even fear about labor and motherhood.
Nesting Instinct
Many women experience a strong urge to prepare for the baby’s arrival, known as the “nesting instinct.” This may involve organizing the nursery, shopping for baby supplies, and cleaning the house. While this can be a positive and productive experience, it is essential to avoid overexertion.
Anxiety and Anticipation
As the due date approaches, feelings of anxiety about labor and delivery may arise. It is natural to have concerns about the birthing process and how life will change after the baby arrives. Engaging in relaxation techniques, such as prenatal yoga or meditation, can help manage these feelings.
Baby’s Development
Growth and Development
During the third trimester, the baby undergoes significant growth and development. By the end of the trimester, the average baby weighs about 5 to 8 pounds (2.3 to 3.6 kg) and measures about 18 to 20 inches (46 to 51 cm) in length. The baby continues to gain weight and develop body fat, which is essential for regulating body temperature after birth.
Organ Maturation
The baby’s organs continue to mature during this stage. The lungs develop further, preparing for breathing air at birth. The digestive system becomes functional, and the kidneys produce urine. By the end of the third trimester, the baby’s brain undergoes rapid development, with neural connections forming that are crucial for cognitive function.
Positioning for Birth
As the due date approaches, the baby typically moves into a head-down position in preparation for birth. This position is known as vertex presentation. Some babies, however, may be in a breech position (bottom down) or transverse position (sideways). Healthcare providers monitor the baby’s position during regular prenatal visits.
Preparing for Labor and Delivery
Birth Plan
Many expecting mothers choose to create a birth plan to outline their preferences for labor and delivery. This plan can include preferences for pain management, support persons during labor, and immediate postpartum care for the baby. Discussing this plan with healthcare providers can ensure everyone is on the same page.
Packing for the Hospital
As the due date approaches, it’s essential to pack a hospital bag in advance. Items to consider include:
Comfortable clothing: Loose-fitting clothes for after delivery.
Toiletries: Personal hygiene items, such as toothbrush, shampoo, and deodorant.
Baby essentials: An outfit for the baby, receiving blanket, and diapers.
Important documents: Insurance information and any necessary identification.
Prenatal Classes
Many hospitals offer prenatal classes to prepare expecting mothers and their partners for labor and delivery. These classes can cover various topics, including labor signs, breathing techniques, and postpartum care. Attending these classes can provide valuable information and help reduce anxiety about the birthing process.

Signs of Labor
Pre-Labor Symptoms
As the due date approaches, mothers may experience pre-labor symptoms. These can include:
Braxton Hicks Contractions: Irregular, practice contractions that help prepare the uterus for labor.
Lightening: The baby drops lower into the pelvis, which may relieve pressure on the mother’s diaphragm but increase pressure on the bladder.
Cervical Changes: The cervix begins to soften and dilate in preparation for labor.
True Labor Signs
True labor signs indicate that the body is preparing for childbirth. These can include:
Regular Contractions: Contractions become more frequent and consistent. They may feel like menstrual cramps and increase in intensity.
Water Breaking: The amniotic sac may rupture, causing fluid to leak. This is often referred to as “breaking the water.”
Bloody Show: A pink or brown discharge may indicate that the cervix is dilating.
When to Call the Doctor
Expecting mothers should know when to call their healthcare provider or go to the hospital. Signs to watch for include:
Contractions that are 5 minutes apart and lasting for 1 minute for 1 hour.
Sudden loss of fluid (water breaking).
Severe abdominal pain or heavy bleeding.
Any concerning symptoms or changes in the baby’s movements.
Postpartum Preparation
Postpartum Recovery
After delivery, the mother will begin her postpartum recovery. This period can involve physical and emotional adjustments. Understanding what to expect can help ease the transition.
Physical Recovery
Physical recovery varies for each woman. Common experiences may include:
Uterine Contractions: The uterus contracts as it returns to its pre-pregnancy size, which may cause discomfort.
Vaginal Discharge: Lochia, or postpartum discharge, occurs as the body sheds the uterine lining. This discharge will gradually decrease over time.
Breast Changes: Milk production begins, and breasts may feel engorged or tender.
Emotional Recovery
Postpartum emotions can fluctuate as hormone levels stabilize. Some women may experience “baby blues,” characterized by mood swings and irritability. However, if feelings of sadness persist or worsen, it is essential to seek help, as this may indicate postpartum depression.
Conclusion
The third trimester of pregnancy is a pivotal time filled with physical and emotional changes as mothers prepare for childbirth. Understanding what to expect can help alleviate anxiety and create a smoother transition into motherhood. Preparing for labor, discussing birth plans, and being aware of the signs of labor are crucial for an empowered birth experience. With the right support and knowledge, expecting mothers can embrace this final stage of pregnancy with confidence and excitement.
