👶 Baby Update

Size: A pin head

If conception happened, the fertilized egg is now a blastocyst — a tiny ball of about 70-100 cells traveling down the fallopian tube toward the uterus. It will implant in the uterine wall by the end of this week.

💕 What She's Going Through

Most women feel nothing. Some notice very light spotting (implantation bleeding) or mild cramping. She might feel slightly more tired than usual.

💪 What You Should Do This Week

  • Keep being supportive and patient — there's nothing to 'do' yet
  • Make sure prenatal vitamins are stocked
  • Avoid any major stressors if possible

🚫 Don't Say This

Let's take a test!

🧠 Dad Hack

Implantation bleeding looks different from a period — it's lighter, pinkish, and lasts 1-2 days. Don't panic if she spots a little.
