The fingers and toes have fully separated, and the webbing between them is gone. Hair follicles are forming across the body, the ears are moving into their final position on the sides of the head, and the nasal passages are open. The fetus can already stretch and somersault inside the amniotic sac.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Some people notice nausea starting to ease this week, while others need a bit longer. Skin can be unpredictable — clearer for some, breakouts for others — and gums may bleed a little when brushing because they are more sensitive. Appetite often begins to return as the first trimester winds down.

At 11 weeks 0 days you are 77 days into a 280-day pregnancy, which leaves 203 days — 29 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 the second trimester (14 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 11 falls in month 3, in the first 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 — 11+3 or 11w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.

About 29 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 11 weeks 0 days you are 77 days into a 280-day pregnancy, so there are 203 days left until the 40-week mark — that's 29 weeks. The count drops by one for each day you move through week 11.
11 weeks is 77 days, counted from the first day of your last menstrual period (11 × 7 = 77). Add the days into your current week for the exact figure — for example 11 weeks 3 days is 80 days.
