What should pregnant women pay attention to during the first three months of pregnancy?

The first three months of pregnancy are a critical period for embryonic development. Special attention should be paid to the following points: 1. **Healthy diet**: Maintain a balanced intake of nutrients, eat more fresh vegetables and fruits, and moderately increase the consumption of protein, folic acid, and other nutrients. Avoid raw meat, raw fish, and high-mercury foods to prevent anemia. 2. **Regular作息**: Ensure adequate sleep and avoid fatigue, which helps promote healthy fetal development. 3. **Folic acid supplementation**: Take folic acid as directed by a physician to prevent fetal neural tube defects. 4. **Avoid harmful substances**: Stay away from secondhand smoke, toxic chemicals, radiation, etc. Wear radiation-shielding clothing to protect fetal safety. 5. **Prevent infections**: Maintain personal hygiene, avoid crowded or unclean environments, and reduce the risk of disease transmission. 6. **Adequate rest**: Reduce strenuous exercise, avoid lifting heavy objects, and maintain a relaxed and pleasant state of mind and body. 7. **Regular prenatal checkups**: Establish a prenatal medical record promptly and monitor embryonic development.
