Pregnancy Week 28: Beginning the Third Trimester
Pregnancy week 28 marks the beginning of the third trimester, the final stage of pregnancy. During this period, your baby continues growing rapidly while your body prepares for labor and delivery in the coming weeks.
Many women begin noticing stronger and more frequent baby movements during this stage. Kicks, stretches, and rolling sensations may become easier to feel as your baby becomes stronger.
Entering the third trimester can bring a mix of excitement and anticipation. Although your baby still has important development ahead, many of the major systems in the body are already functioning and continuing to mature.
Baby Development at Week 28
At twenty-eight weeks pregnant, your baby is about the size of an eggplant and continues growing steadily each week.
Your baby’s brain is developing rapidly during this stage. The brain is forming more complex connections that help support learning, movement, and sensory development.
Your baby’s nervous system continues maturing as nerve pathways strengthen and communication between the brain and body improves.
Your baby’s eyes can now open and close, and the baby may begin responding to light from outside the womb. Some babies may turn their heads or move when exposed to bright light.
Your baby is also developing more regular sleep and wake cycles. These cycles may not match your own schedule, which is why babies sometimes seem more active when you are resting.
Fat continues accumulating beneath the baby’s skin, helping the body become rounder and preparing the baby to regulate body temperature after birth.
Your baby’s lungs are continuing to develop as well. Although they are still maturing, they are gradually preparing for breathing after delivery.
Common Symptoms During Week 28
Common experiences during week 28 include:
Shortness of breath
Back discomfort
Fatigue
Stronger baby movements
Occasional leg cramps
Shortness of breath may occur because the growing uterus places pressure on the diaphragm and lungs. This can make breathing feel slightly more difficult, especially during physical activity.
Back discomfort is also common as the growing baby bump changes posture and places additional strain on the lower back.
Fatigue may return during this stage of pregnancy as your body continues working hard to support your baby’s growth.
Although these symptoms can feel uncomfortable, they are usually a normal part of the third trimester.
Changes in Your Body
As your baby continues growing, your uterus expands upward and may place pressure on nearby organs.
Your center of gravity may shift further forward as your abdomen grows larger. This shift may affect balance and posture.
Your body is also producing increased blood volume to supply oxygen and nutrients to your baby through the placenta.
Some women may notice mild swelling in the feet, ankles, or hands during this stage due to increased circulation.
Your baby bump may also become more noticeable as you move further into the final trimester.
Understanding Baby Movements
By week 28, many babies move frequently throughout the day. Some babies may become more active during certain times, such as after meals or when the mother is resting.
You may begin noticing patterns in your baby’s activity as the weeks progress.
Regular baby movements are often reassuring and are a normal sign of healthy development.
Every pregnancy is different, and movement patterns can vary from baby to baby.
Helpful Tips for Week 28
Take breaks throughout the day when needed
Sleep on your side to improve circulation
Stay hydrated
Continue gentle physical activity such as walking
Sleeping on your side is often recommended during the later stages of pregnancy because it helps support blood flow to the baby.
Taking time to rest and staying hydrated can also help manage fatigue and support overall health.
