Quick Answer
A full-term pregnancy lasts 40 weeks across three trimesters: weeks 1–12 (first), weeks 13–26 (second), and weeks 27–40 (third). Babies born at 37 weeks or later are considered full-term by WHO definition. Most mothers feel best in the second trimester when morning sickness typically eases and energy returns.
