What's Happening With Your Baby
The brain is growing rapidly — around 100 new brain cells a minute this week. Hand and foot plates are forming, with the fingers still webbed. The kidneys move into place and urine production begins.
What's Changing For You
Your uterus has doubled in size, though your belly doesn't show yet. Your skin may become oilier or break out. Nausea peaks for most women around now.
To Do This Week
If smells trigger nausea, try eating food cold or at room temperature.
Vitamin B6 can help with nausea — ask your doctor about the dose.
Increase fibre and water for constipation, and make walking part of your routine.
Frequently Asked Questions
How many months is 7 weeks pregnant?
Week 7 of pregnancy falls in month 2 and in the first trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 7 weeks?
At 7 weeks your baby is roughly the size of a blueberry: around 1.3 cm long and 1 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 7 weeks pregnant?
Assuming a 40-week pregnancy, you have around 33 weeks left at week 7. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 7 weeks?
If smells trigger nausea, try eating food cold or at room temperature. Vitamin B6 can help with nausea — ask your doctor about the dose. Increase fibre and water for constipation, and make walking part of your routine.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
