How your baby is growing this week
Poppy-seed size — about 0.04 inches. Implantation is complete, and the embryo has organized into three layers that will form every organ, bone, and nerve. The neural tube — the foundation of the brain and spinal cord — is beginning to form this week and next.
What your partner is going through
Missed period confirmed. hCG doubling every 48 hours — causing fatigue, breast tenderness, and possible nausea. Emotional whiplash between excitement and terror is standard.
What to focus on this week, dad
- 01Start the Protocol folder — one shared Google Drive or Notion doc for insurance cards, OB contact, pharmacy, appointment notes, and the questions you'll accumulate fast. Everything for the next nine months lives in one place.
- 02Calculate the due date (last period + 280 days) and count backward now to map your parental leave. The earlier you flag the timeline to your employer, the smoother it goes.
