The heart tube has folded and begun beating at around 100–160 beats per minute, pumping blood through a simple circuit. Dark spots mark where the eyes and nostrils will be, and small pits on the sides of the head are the beginnings of the ears. The embryo is curled in a C-shape, so measurements are taken from crown to rump.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Morning sickness — which can strike at any time of day — often begins around now, and food aversions can be sudden and strong. Your breasts may feel fuller and heavier, with darker areolas. Some people also feel emotionally up and down as hormone levels change quickly.

days so far
At 6 weeks 0 days you are 42 days into a 280-day pregnancy, which leaves 238 days — 34 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: 56 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 6 falls in month 2, 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 — 6+3 or 6w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.

At 6 weeks pregnant, you are about 2 months pregnant — in month 2 of your pregnancy and in your first trimester. Months of pregnancy are counted as uneven 4–5 week buckets so that the full 40 weeks fits into 9 calendar months.
6 weeks is in the first trimester, which runs from week 0 through 13 weeks 6 days. The second trimester begins at 14 weeks 0 days.
About 34 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 6 weeks 0 days you are 42 days into a 280-day pregnancy, so there are 238 days left until the 40-week mark — that's 34 weeks. The count drops by one for each day you move through week 6.
6 weeks is 42 days, counted from the first day of your last menstrual period (6 × 7 = 42). Add the days into your current week for the exact figure — for example 6 weeks 3 days is 45 days.
