The brain is growing at a remarkable pace, and little paddle-shaped limb buds are on their way to becoming arms and legs.

The brain is dividing into its three main sections — forebrain, midbrain and hindbrain — and the head is growing faster than anything else. Tiny nostrils appear, the lenses of the eyes are forming, and the arm buds are already flattening into paddle shapes that will become hands. The umbilical cord is now a working connection between embryo and placenta.
Sizes and weights are averages — healthy babies vary widely, and your scan measurements are what count.
Fatigue can feel overwhelming this week; your body is building a placenta and increasing blood volume at the same time. Saliva may increase, and mild bloating or constipation is common as digestion slows under progesterone. Weight is usually unchanged so far, and losing a little from nausea is not unusual.

At 7 weeks 0 days you are 49 days into a 280-day pregnancy, which leaves 231 days — 33 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: 49 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 7 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 — 7+3 or 7w3d, for example. Pick the exact day you are on for its own day count, countdown and month answer.

At 7 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.
7 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 33 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 7 weeks 0 days you are 49 days into a 280-day pregnancy, so there are 231 days left until the 40-week mark — that's 33 weeks. The count drops by one for each day you move through week 7.
7 weeks is 49 days, counted from the first day of your last menstrual period (7 × 7 = 49). Add the days into your current week for the exact figure — for example 7 weeks 3 days is 52 days.
