The digestive system is fully developed but has never processed food, so it will keep maturing after birth. Gums are firm with ridges where teeth will emerge, and the ears are sharp enough to recognize familiar voices and songs. Circulation and the immune system are ready enough to work outside the womb.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
If the head has engaged, breathing and eating may feel easier while pressure on the bladder and pelvis increases — this is often called lightening. Walking can become a waddle as the pelvic joints loosen. Sleep is patchy, and many people feel a mix of impatience and nerves.

At 36 weeks 0 days you are 252 days into a 280-day pregnancy, which leaves 28 days — 4 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: 7 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 36 falls in month 9, 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 — 36+3 or 36w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.

About 4 weeks until the 40-week mark — though only about 1 in 20 babies arrives exactly on the due date. Most are born within two weeks on either side of it.
