Understanding Pregnancy Weeks

Pregnancy is typically calculated from the first day of your last menstrual period (LMP) and lasts about 40 weeks. These weeks are divided into three trimesters, each bringing unique changes and developments for both you and your baby.

The first trimester (weeks 1-12) is crucial for your baby's development. Major organs and structures begin to form, and you might experience various pregnancy symptoms. The second trimester (weeks 13-26) is often called the "golden period" of pregnancy, when many women feel their best. The third trimester (weeks 27-40) focuses on your baby's rapid growth and preparing for birth.
