Week 1
The garden begins with A seed, held: not a size comparison, but a quiet picture of possibility before anything has been planted.

How big is the baby at 1 weeks?
No size is stated at week 1. Pregnancy is dated from the first day of your last period, so the earliest weeks come before there is anything to measure — this page says so rather than inventing a comparison.
Pregnancy is dated from the first day of the last menstrual period, so the first week on the pregnancy calendar is counted even though conception has not happened yet. There is no embryo to measure this week.1
1 weeks pregnant is how many months?
Week 1 falls in the first month of pregnancy. Weeks and months don’t divide evenly, and your antenatal care counts in weeks — so Zohra keeps weeks, and prints the month for the relatives who ask.
That puts you in the first trimester (weeks 1–13).
What might you be noticing?
There is no pregnancy-specific symptom pattern yet because this counted week comes before conception. Whatever the week feels like belongs to your own cycle, and it does not need to resemble anyone else's beginning.1
Choose one private place for dates, questions, and notes. If you want a keepsake, photograph something ordinary from this week—the view from a window, a book on the table, the weather outside.
For the record: What was life holding before you knew this story had begun? — this week’s page in the app asks the same thing. All forty prompts are here.
