Frequently asked
What does 9 weeks pregnant mean in days and months?
9 weeks is 63 days since the first day of your last period, which is about 3 months pregnant on the four-week-per-month convention. 217 days remain in the 40-week count from here — that is 23% of the way through.
How big is a baby at 9 weeks?
Around the size of a cherry, at about 0.35 g. These are population averages: a scan measurement that differs by a few days is normal and does not by itself mean anything is wrong.
Which trimester is week 9?
The 1st trimester. The split used here is the same one the calculator applies: the first trimester covers days 1–90, the second 91–195, and the third from day 196 onward. Other sources draw the boundary a week either side, which is why week 13 and week 14 can both be described as "end of the first trimester".
What appointments happen after week 9?
Next up: NT scan (combined test) at 11–13 weeks, Quad / anomaly blood screen at 15–20 weeks, Anatomy scan at 18–22 weeks. The full schedule is in the table above; exact timing varies by country and by your care team.
