What is the duration of the second trimester?

The correct duration of the second trimester is from the 12th to the 28th week of pregnancy. This timeframe marks a significant period for both the mother and the developing fetus. The second trimester is often referred to as the "golden period" of pregnancy because many women experience relief from early pregnancy symptoms such as nausea and fatigue. Additionally, this trimester is crucial for fetal growth and development, as various organs and systems undergo significant maturation.

Understanding the structure of pregnancy trimesters is important in clinical practice, as it helps healthcare providers monitor the progress of both maternal and fetal health. The first trimester, from conception up to the end of the 12th week, is characterized by initial development and implantation. The third trimester, which begins after the 28th week and goes until delivery, involves rapid fetal growth and preparation for birth. Therefore, identifying the specific weeks associated with each trimester is essential for providing appropriate care and education to expectant mothers.
