Welcome to week 6. Your baby is growing fast and your body is changing. This week we cover development milestones, common symptoms, and what to prepare next as you move through your first trimester.

Ask an expertQuestion of the week

Is it normal to feel exhausted in the first trimester?

Yes β€” hormonal shifts (especially rising progesterone) plus the metabolic cost of building a placenta make first-trimester fatigue one of the most common symptoms. Rest when you can, prioritize iron-rich foods, and bring it up at your next appointment if it feels extreme or comes with shortness of breath.

Frequently asked β€” 6 Weeks Pregnant

How many months is 6 weeks pregnant?+

6 weeks is roughly 1 months pregnant. Pregnancy is most precisely tracked in weeks (40 weeks total from your last period), since "months" don’t divide evenly into weeks.

When is my due date if I'm 6 weeks pregnant?+

With 34 weeks to go, your estimated due date is about 34 weeks away. Due dates are estimates β€” only about 1 in 20 babies arrive exactly on the date, with most born within two weeks either side.
