How your baby is growing this week
If fertilized, the zygote has divided into a ball of about 100 cells called a blastocyst. It's traveling down the fallopian tube toward the uterus. By end of the week, implantation begins — the blastocyst burrows into the uterine wall and hCG production starts.
What your partner is going through
No noticeable symptoms yet for most women. Some may experience light spotting (implantation bleeding) or mild cramping that feels like a period starting. hCG levels are still too low for a home pregnancy test to detect reliably.
What to focus on this week, dad
- 01Don't test yet — it's too early and a false negative will just add stress. hCG needs to build for a reliable result
- 02Set up a shared notes system — Google Doc, Notion, Apple Notes, whatever works — for questions, appointments, and research you'll accumulate fast
