The lips are more defined and the first signs of tooth buds are visible under the gums. The eyes are complete but the iris still lacks pigment, so eye color is not set yet. The pancreas is developing steadily, and grip strength is improving as the fetus grabs the umbilical cord.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Your bump is now clearly noticeable, and strangers may begin to comment. Braxton Hicks contractions — painless tightening of the uterus — can start any time from now and are a normal rehearsal. Feet and ankles may swell more by day’s end, and skin tags or an outie belly button are common.

At 22 weeks 0 days you are 154 days into a 280-day pregnancy, which leaves 126 days — 18 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: 42 days until the third trimester (28 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 22 falls in month 5, in the second 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 — 22+3 or 22w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.
