If you are 12 weeks pregnant, you are approximately 2 months and 22 days. The conversion isn't always perfectly clean because pregnancy lasts 40 weeks but the calendar uses 12 months — the standard medical convention is 4.345 weeks per month. Here's everything you need to know about week 12.

How weeks-to-months conversion works
Pregnancy is counted in weeks, not months, because weeks are more precise. To convert: divide the week count by ~4.345 (the average weeks per month over a 9-month, 40-week pregnancy). For week 12: 12 ÷ 4.345 ≈ 2 months and 22 extra days.
Trimester at week 12
Week 12 falls in the First trimester (weeks 1–13). The first trimester is when major organ formation happens and morning sickness peaks.
