28 Weeks Pregnant: Welcome to the Third Trimester

Week 28 marks the beginning of the third trimester — the final and often most physically demanding stretch of pregnancy. Your baby is now capable of more complex brain activity, and your body is shifting into a more closely monitored phase of care.

What's Happening With Your Baby This Week

About the size of a large eggplant, your baby is entering an active, rapidly maturing phase:

• Eyes can now open and close, with regular blinking as a normal part of your baby's activity.
• The brain is developing rapidly, with increasingly complex patterns of activity — some research suggests babies may even begin experiencing early dream-like REM sleep.
• Lungs continue maturing, steadily improving readiness for life outside the womb, though they're not yet fully developed.
• Weight gain accelerates significantly from this point forward, as your baby builds the fat stores needed after birth.
• Your baby may settle into a more consistent position, which your doctor will begin monitoring more closely.

Why Kick Counting Often Starts Now

Many doctors recommend beginning daily movement tracking, sometimes called "kick counts," starting around week 28. This simply means paying attention to your baby's usual activity pattern each day — not counting every single movement, but noticing what's normal for your baby.

Practical tip: Ask your doctor for their specific kick-count guidance, as methods vary — some recommend counting to 10 movements within a set time window, once or twice daily.

What's Happening In Your Body

• Prenatal appointments typically become more frequent from here, often shifting to every two weeks.
• Heartburn and indigestion often increase as the growing uterus puts more pressure on the stomach.
• Backaches and pelvic pressure commonly intensify as your baby continues growing.
• Sleep can become more difficult due to physical discomfort, frequent urination, and a growing bump.
• If you're Rh-negative, your doctor may discuss a preventive injection (anti-D) typically given around this stage.

What You Should Do This Week

• Ask your doctor about kick-count guidance and start building daily awareness of your baby's movement patterns.
• Discuss your Rh factor with your doctor if you don't already know your blood type status.
• Manage heartburn with smaller, more frequent meals and by avoiding lying down right after eating.
• Continue prenatal vitamins and prioritize rest as fatigue may return.
• Begin light preparation for more frequent appointments and the physically demanding weeks ahead.

Frequently Asked Questions

What counts as a "normal" number of kicks per day?
There's no single universal number — the goal is recognizing your baby's own typical pattern, then noticing if it changes significantly. Your doctor can give specific guidance for your pregnancy.

Should I be worried if I feel fewer movements some days?
Occasional quieter days can be normal, but a significant, sustained decrease in movement should always be reported to your doctor promptly rather than waiting.

What is the anti-D injection, and why is it needed?
It's a preventive treatment given to Rh-negative parents to prevent potential complications related to blood type differences between parent and baby. Your doctor will explain if and when it applies to you.

Is heartburn during the third trimester normal?
Yes, very common, caused by the growing uterus pressing on the stomach combined with hormonal effects on digestion. Smaller meals and avoiding trigger foods often help.
