How much time taken in pregengy mostly?

Pregnancy typically lasts about 40 weeks, or roughly nine months, calculated from the first day of the last menstrual period. It is divided into three trimesters: the first trimester (weeks 1-12), the second trimester (weeks 13-26), and the third trimester (weeks 27-40). However, full-term pregnancies can range from 37 to 42 weeks. Each pregnancy is unique, and some may result in slightly shorter or longer durations.
