A complete week-by-week pregnancy due date calculator breakdown — what's happening in each stage of the 40-week journey.
Weeks 1–13 · Month 1–3
Conception, implantation, and the rapid formation of every major organ system. You'll likely confirm pregnancy, hear the first heartbeat around week 6–8, and complete the first ultrasound by week 12.
Baby goes from a poppy seed (week 4) to a lemon (week 13).
Weeks 14–27 · Month 4–6
The "honeymoon trimester." Energy returns, the bump becomes visible, and you'll feel first movements between weeks 18–22. The detailed anatomy scan happens around week 20.
Baby goes from a peach (week 14) to a rutabaga (week 27).
Weeks 28–40 · Month 7–9
Baby gains weight rapidly and prepares for birth. You'll have biweekly then weekly checkups, glucose screening, Group B strep testing, and the nesting instinct kicks in. Full term is week 37.
Baby goes from an eggplant (week 28) to a small pumpkin (week 40).
