Welcome to 28 weeks! This marks an exciting milestone – the official start of your third trimester. You’re getting closer to meeting your little one, and both you and your baby are experiencing significant changes. Let’s explore what this week might bring.
Your Baby at 28 Weeks

At 28 weeks, your baby is growing steadily and refining many important systems. They’re typically about the size of an eggplant, weighing around 2.5 pounds and measuring about 15 inches from head to heel. Here’s what’s happening inside:

- Eyes Open! For the first time, your baby can open their eyes and see light filtering through the uterine wall. They might even turn their head toward a bright light source.
- Brain Development: The brain is developing rapidly, forming billions of neurons and creating distinct grooves and indentations on its surface, which are crucial for increased brain power.
- Fat Layers: Your baby is continuing to lay down layers of fat, which will help them regulate their body temperature after birth. This also makes their skin appear less transparent.
- Breathing Practice: While still in amniotic fluid, your baby is practicing breathing motions, inhaling and exhaling small amounts of fluid, which helps develop their lungs.
- Sleep Patterns: Your baby is developing more distinct sleep-wake cycles, and you might notice periods of increased movement followed by quiet spells.
What Happens to You at 28 Weeks?
The third trimester brings its own set of sensations and preparations. You might feel more tired, and your body is working hard to support your growing baby.

- Third Trimester Begins: You’ve officially entered the home stretch! This is a good time to start thinking about birth plans and what to expect in the coming weeks.
- Braxton Hicks Contractions: You might experience more frequent Braxton Hicks contractions. These are usually mild, irregular uterine tightenings that help prepare your body for labor. If they become regular, painful, or increase in intensity, contact your healthcare provider.
- Fatigue: As your belly grows and your body works harder, renewed fatigue is common. Listen to your body and rest when you can.
- Round Ligament Pain: Sharp pains in your lower abdomen or groin might occur as the ligaments supporting your uterus stretch.
- Glucose Screening: If you haven’t already, your healthcare provider will likely recommend a glucose screening test around this time to check for gestational diabetes.
- Rhogam Shot (if applicable): If you are Rh-negative, you’ll likely receive a Rhogam shot this week or soon after. This prevents your body from producing antibodies against your baby’s Rh-positive blood.

Is 28 weeks really the start of the third trimester?
Yes, generally, the third trimester is considered to begin at week 28 and continues until birth.
What are some red flags I should watch out for?
Always contact your healthcare provider if you experience severe headaches, sudden swelling in your face or hands, changes in vision, severe abdominal pain, vaginal bleeding, leaking amniotic fluid, or a significant decrease in fetal movement. These could be signs of complications that require immediate medical attention.
How often should I feel my baby move?
Your baby’s movements should become more regular and noticeable. While there’s no magic number, many providers recommend monitoring your baby’s movements and looking for a consistent pattern. If you notice a significant decrease or change in your baby’s usual movement pattern, contact your healthcare provider right away.
