Introduction
In early pregnancy, embryonic development is still unstable and the mother is susceptible to external factors. Excessive fatigue may lead to various discomforts, including persistent tiredness and weakness, abnormal vaginal bleeding, significant lower back soreness and abdominal pain, poor sleep quality, and severe mood swings. When these symptoms occur, it is important to rest and adjust promptly. Pregnant women should maintain a reasonable daily routine during early pregnancy and avoid prolonged standing.

During early pregnancy, embryonic development is still unstable, and the mother is susceptible to external factors. Excessive fatigue may lead to various discomforts, including persistent tiredness, abnormal vaginal bleeding, noticeable lower back pain and abdominal pain, poor sleep quality, and severe mood swings. When these symptoms occur, timely rest and adjustment are necessary. Detailed explanations are as follows:

1. Persistent fatigue and weakness: Fatigue is common in early pregnancy, and excessive exertion can intensify this sensation. It manifests as generalized body aches, weak limbs, and a lack of energy that persists even after prolonged rest. Simple daily activities such as walking or doing household chores may cause obvious shortness of breath and difficulty concentrating.

2. Abnormal vaginal bleeding: This is a symptom requiring high alert. Excessive fatigue may stimulate uterine contractions, leading to spotting or brownish discharge. Although the amount is usually small, it may recur frequently. If accompanied by abdominal pain, all physical activity should be stopped immediately, and rest is essential to prevent further complications.

3. Noticeable lower back pain and abdominal pain: Overexertion increases strain on the lower back, causing persistent dull aching. The abdomen may feel slightly heavy or experience mild cramping—this is the uterus’s response to physical stress. If the pain worsens or becomes rhythmic, prompt medical attention is needed.

4. Decreased sleep quality: Excessive fatigue disrupts the body's normal rhythm, making it difficult to fall asleep, causing light sleep, frequent awakenings at night, and difficulty returning to sleep afterward. Chronic poor sleep further exacerbates fatigue, creating a vicious cycle that negatively affects both maternal health and fetal development.

5. Severe mood swings: Physical exhaustion impacts mental well-being, making pregnant women unusually sensitive during early pregnancy. They may become irritable, anxious, or depressed, overreact to minor issues, and struggle to control their emotions. In severe cases, this can affect hormonal balance.

In early pregnancy, it is important to maintain a reasonable daily routine, avoid prolonged standing, staying up late, or engaging in heavy physical labor. Prompt rest should be taken when feeling fatigued, and relaxation techniques such as listening to music or meditation can help ease both mind and body. A diet rich in high-quality protein and vitamins provides sufficient energy and supports the health of both mother and baby.
