Tiny Beginnings, Big Changes

Welcome To Weeks 1–3!

Your body is preparing for pregnancy, with early calculation starting from your last period before official conception.

Pregnancy calculation begins from the first day of your last period.
Ovulation typically occurs around day 14, with peak fertility between days 12–14.
Released eggs survive 24 hours, while sperm survives up to 72 hours.
Baby is in the microscopic fertilization and early cellular stage.

Changes in Your Body

No noticeable changes yet, you’re still having your period at the start of this window.
Around ovulation, some notice mild pelvic twinges or increased cervical mucus.
Hormone levels then begin to rise after conception, though there’s still nothing visible on the outside.

What's Happening Inside?

Pregnancy is dated from the first day of your last period, so conception hasn’t happened yet at the start of this window.
Ovulation and fertilization occur around week 2-3, and by the end of week 3 the fertilized egg is a tiny cluster of dividing cells travelling to the womb.

When to Check With a Doctor

• Heavy bleeding or spotting with pain.
• Severe abdominal or pelvic pain.
• High fever (above 38°C).
• Persistent vomiting or inability to keep fluids down.
