The vernix coating is thickening to protect the skin, and fingernails have reached the fingertips. The central nervous system and lungs are maturing quickly, and the fetus’s eyes are more responsive to light. In boys, the testicles have usually completed descent by now.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Fatigue, swelling and pelvic pressure are common as the baby moves lower. Vision changes such as blurriness may occur and typically resolve postpartum. Some people experience heightened anxiety or vivid dreams as delivery nears.

days so far
At 34 weeks 0 days you are 238 days into a 280-day pregnancy, which leaves 42 days — 6 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: 21 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 34 falls in month 8, 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 — 34+3 or 34w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.

34 weeks is in the third trimester, which runs from 28 weeks 0 days until birth. Full term begins at 39 weeks 0 days.
About 6 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.
At 34 weeks 0 days you are 238 days into a 280-day pregnancy, so there are 42 days left until the 40-week mark — that's 6 weeks. The count drops by one for each day you move through week 34.
34 weeks is 238 days, counted from the first day of your last menstrual period (34 × 7 = 238). Add the days into your current week for the exact figure — for example 34 weeks 3 days is 241 days.
