Understanding Pregnancy Trimesters
Pregnancy typically lasts about 40 weeks and is divided into three trimesters. Each trimester represents a unique stage of fetal development and physical changes in the mother's body.
First Trimester (Weeks 1–12)
During the first trimester, the fertilized egg implants into the uterus and begins forming major organs such as the heart, brain, and lungs. Many women experience symptoms such as nausea, fatigue, and hormonal mood changes.
Second Trimester (Weeks 13–26)
The second trimester is often considered the most comfortable stage of pregnancy. The baby continues to grow rapidly, and fetal movements may start to be felt. Ultrasound scans are usually performed during this period to assess fetal development.
Third Trimester (Weeks 27–40)
In the final trimester, the baby gains weight and prepares for birth. Mothers may experience increased physical discomfort, sleep difficulty, and Braxton Hicks contractions as the body prepares for labor.
Medical Guidance
The World Health Organization emphasizes the importance of regular prenatal care throughout pregnancy. Monitoring maternal health and fetal development helps identify potential complications early and supports safe pregnancy outcomes.
