A trimester is a period of roughly three months in a pregnancy, dividing the pregnancy into three stages. The first trimester covers weeks 1 to 12 and is when the baby’s major organs and structures begin to form. The second trimester lasts from weeks 13 to 26 and is marked by significant growth and development of the baby, along with noticeable changes in the mother’s body. The third trimester includes weeks 27 to birth, during which the baby continues to grow and mature, and the mother prepares for labor and delivery. Each trimester marks different stages of the baby's development and changes in the mother's body.
- The first trimester is crucial for early fetal development.
- The second trimester is often considered the most comfortable for expectant mothers.
- The third trimester involves significant fetal growth and preparation for birth.
- The healthcare provider monitors maternal and fetal health throughout the trimesters.
- Symptoms like morning sickness are common in the early trimesters.
