The fetus can blink and has eyelashes, and the eyes may follow a light source. Fat is filling out the body, and the brain surface is developing grooves and folds. Breathing movements are more rhythmic, and the fetus can now regulate its own temperature to a small degree.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Third-trimester symptoms often ramp up together: shortness of breath, back pain, difficulty sleeping and swelling in the ankles. Some people feel emotional or anxious about the birth ahead. Sciatica can flare as the baby’s head presses lower.

At 28 weeks 0 days you are 196 days into a 280-day pregnancy, which leaves 84 days — 12 weeks — until 40 weeks. That number drops by one for every day you move through this week. Remember the due date is an estimate: only about 1 in 20 babies is born on it, and most arrive within two weeks on either side.
Next milestone: 63 days until early term (37 weeks 0 days).
A calendar month averages about 4.3 weeks — not 4 — so you can't just divide your week number by four. Instead, months of pregnancy are counted as uneven buckets of 4 to 5 weeks, arranged so the full 40 weeks fits into 9 calendar months. Week 28 falls in month 7, in the third trimester.
Your care team will always use weeks and days rather than months, because screening windows and term definitions are set by exact week — months are just the everyday shorthand. For the full conversion, see the weeks to months chart, or go the other way with the months-to-weeks guide.
Your notes will show a week and a day — 28+3 or 28w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.
