How Pregnancy Weeks Are Counted
Pregnancy is counted from the first day of your last menstrual period (LMP), even though conception typically occurs about 2 weeks later. A full-term pregnancy is 40 weeks (280 days). Weeks are grouped into trimesters:
- First trimester: Weeks 1–12
- Second trimester: Weeks 13–26
- Third trimester: Weeks 27–40
