28 Weeks Pregnant

28 weeks pregnant: third trimester, baby size and movement

At 28 weeks pregnant, you are entering the third trimester in many pregnancy calendars. This week follows 27 weeks pregnant, and the next page is 29 weeks pregnant.

Your baby may weigh about 1-1.5 kg and measure around 30-35 cm, though individual growth varies. Movements are often stronger now, and you may notice kicks, stretches, rolls or rhythmic hiccup-like movements.

The baby can react to light by blinking, the skin is no longer transparent, and fat continues building under the skin. The brain, lungs and temperature control are still maturing, so every extra week in the womb is valuable even though neonatal care outcomes improve greatly at this stage.

Your body at 28 weeks pregnant

The uterus is moving closer to the rib cage, which can make heartburn, indigestion or breathlessness more noticeable. Eating smaller meals, drinking fluids between meals and avoiding very spicy or greasy foods may help.

Colostrum leakage from the breasts can start or increase. Vaginal discharge may also increase, but it should not smell unpleasant, cause strong itching, or look like fluid leaking continuously. Ask your clinician if you are unsure.

Your maternity team may check blood pressure, urine, weight, swelling, fundal height and the baby's heartbeat more regularly from this stage. Blood tests, glucose screening follow-up, Rh antibody checks or extra ultrasound scans may be recommended depending on your care plan.

What to do this week

  • Learn your provider's guidance for monitoring baby movements and when to call.
  • Plan practical purchases gradually, starting with safe sleep, feeding, nappies and hospital bag essentials.
  • Use pillows and side sleeping positions to support your bump, hips and back.
  • Use the pregnancy calculator for date estimates, but follow the due date confirmed by your clinician.

Definitions

Colostrum is the first milk produced by the breasts. It is thick, nutrient-rich and may leak before birth.

Fundal height is the distance from the pubic bone to the top of the uterus. It helps clinicians follow growth trends.

Hiccups can feel like small rhythmic movements in the womb and are usually a normal part of fetal activity.
