Pregnancy Milestones: Key Moments Week by Week

The Journey of a Lifetime

Pregnancy is filled with amazing moments. Here is a timeline of the major milestones you can look forward to.

Weeks 4-6: The Spark of Life

• Week 4: The positive test! Your body is producing enough hCG to be detected.
• Week 6: The heart begins to beat. It's tiny, but it's pumping blood. This is often when it can first be seen on an early ultrasound.

Weeks 8-12: Taking Shape

• Week 8: Fingers and toes are forming, though they might still be webbed.
• Week 10: The "embryonic" period ends. Your baby is now officially a fetus.
• Week 12: The risk of miscarriage drops significantly. Many parents choose to share their news around this time.

Weeks 16-20: Discovery

• Week 16: Gender might be visible! If the baby cooperates, an ultrasound tech might be able to tell if it's a boy or girl.
• Week 18-22: Quickening. You feel those first flutters of movement. It feels like butterflies or gas bubbles.
• Week 20: The Anatomy Scan. This is a detailed check-up to measure the baby and check all organs.

Weeks 24-28: Viability

• Week 24: Viability. This is a huge medical milestone. Babies born at 24 weeks have a chance of survival in a NICU.
• Week 28: Welcome to the third trimester. The baby can open and close their eyes.

Weeks 32-37: Getting Ready

• Week 32: Practice breathing. The baby is practicing the movements of breathing to strengthen their diaphragm.
• Week 36: The baby usually turns head-down (vertex) to prepare for birth.
• Week 37: Early Term. The baby is considered fully developed, though staying in longer is better for lung maturity.

Week 40: The Due Date

The finish line! But remember, it's just an estimate. Your baby will arrive when they are ready.
