What's Happening With Your Baby
The third trimester begins. The baby can open and close their eyes and responds to light. Weight gain is speeding up. Folds are forming on the surface of the brain.
What's Changing For You
Appointments move to every two weeks. Breathlessness, heartburn and frequent urination increase. If you're Rh negative, it's time for your Rh immunoglobulin injection.
To Do This Week
If your blood type is Rh negative, have your Rh immunoglobulin injection in this period.
Start daily movement counts: at least 10 movements in two hours is the expectation.
Begin packing your hospital bag so it's ready by week 36.
This Week's Checkup
For Rh-negative mothers, Rh immunoglobulin is usually given at week 28.
Frequently Asked Questions
How many months is 28 weeks pregnant?
Week 28 of pregnancy falls in month 7 and in the third trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 28 weeks?
At 28 weeks your baby is roughly the size of a aubergine: around 37.6 cm long and 1005 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 28 weeks pregnant?
Assuming a 40-week pregnancy, you have around 12 weeks left at week 28. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 28 weeks?
If your blood type is Rh negative, have your Rh immunoglobulin injection in this period. Start daily movement counts: at least 10 movements in two hours is the expectation. Begin packing your hospital bag so it's ready by week 36.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
