Pregnancy Week 1

The very beginning — here's what's actually happening.

👶 Your baby this week

Week 1 counts from the first day of your last period — conception hasn't happened yet. Your body is preparing an egg for ovulation.

💛 How you might feel

A normal period. Pregnancy math starts here because ovulation dates are hard to pin down.

✅ This week's to-do

Start a prenatal vitamin with folic acid if you haven't already — it matters most in the earliest weeks.

Please note: General information, not medical advice. Every pregnancy is different — your provider's guidance always wins.
