Which trimester involves weeks 14 to 26 of pregnancy?

The second trimester of pregnancy encompasses the weeks from 14 to 26. This period is significant for several reasons, including physiological changes that the body undergoes as it adapts to the growing fetus. During the second trimester, many women experience a decrease in early pregnancy symptoms, such as nausea and fatigue, and may begin to notice physical changes like a growing belly. This trimester is often associated with increased energy levels and enhanced well-being.

In contrast, the first trimester includes weeks 1 to 13 and is characterized by early pregnancy symptoms and the initial development of the fetus. The third trimester follows, covering weeks 27 to 40, when the fetus continues to grow substantially and prepares for birth. The fourth trimester is not an official term for a trimester during pregnancy; instead, it refers to the first three months after birth when the mother and baby are adjusting to the new life together.
