The Journey

Three trimesters, one at a time

Every pregnancy moves through three chapters. Here's what each one brings — and where to start.

Weeks 1–13

The beginning

First Trimester

Early changes, first symptoms, and the essentials of prenatal care. Rest, nutrition, and your first appointments.

Start here

Weeks 14–27

Finding your rhythm

Second Trimester

The steady middle stretch. Energy often returns, the bump grows, and anatomy scans map your baby's development.

Start here

Weeks 28–40

Almost there

Third Trimester

The final stretch toward birth. Prepare your hospital bag, finalize your plan, and watch for signs of labor.
