Section 2: Stages of the First Trimester
Week 1-4:
- Fertilization and Implantation: The fertilized egg travels down the fallopian tube and implants itself in the uterine lining.
- Embryonic Development: The cells of the embryo begin to divide and differentiate, forming the basic structures of the body.
Week 5-8:
- Organ Formation: The embryo’s major organs start to develop, including the heart, brain, and lungs.
- Morning Sickness: Many women experience nausea and vomiting during this time as hormone levels rise.
Week 9-12:
- Fetal Development: The fetus grows rapidly, and its body parts become more defined.
- 胎动: Some women may start feeling the first subtle movements of the fetus.
Section 3: Signs and Symptoms of the First Trimester
- Missed Period: This is the most common early sign of pregnancy.
- Breast Tenderness: Your breasts may become enlarged and tender as they prepare for milk production.
- Frequent Urination: Increased blood flow to the kidneys leads to more frequent urination.
- Fatigue: The surge in hormones and the body’s increased workload can make you feel tired.
