Introduction
Under normal circumstances, it is difficult to completely rule out fetal cerebral palsy during prenatal examinations. However, regularly scheduled prenatal checkups during pregnancy, monitoring fetal developmental indicators, screening for high-risk factors, tracking fetal movements, and performing imaging examinations can help reduce the risk to some extent. It is recommended to follow the physician's advice and undergo regular prenatal examinations, including tests such as complete blood count (CBC), urinalysis, Down syndrome screening, and non-invasive DNA testing.

Under normal circumstances, it is difficult to completely rule out fetal cerebral palsy during prenatal examinations. However, regular prenatal checkups during pregnancy, monitoring fetal developmental indicators, screening for high-risk factors, tracking fetal movements, and conducting imaging examinations can generally help reduce this risk. Detailed explanations are as follows:

1. Regular prenatal checkups: Follow your doctor's recommendations for regular prenatal examinations, including routine blood tests, urine tests, Down syndrome screening, and non-invasive DNA testing, to promptly detect any abnormalities that might affect fetal brain development, thus providing a basic reference for ruling out cerebral palsy.

2. Monitoring fetal developmental indicators: Use ultrasound to monitor the growth and development of the fetus, checking whether indicators such as head circumference, biparietal diameter, and femur length are within the normal range, to assess whether the fetal brain and overall development match the gestational age and to determine if there is any developmental delay.

3. Screening for high-risk factors: The doctor will inquire about conditions during pregnancy such as hypertension, diabetes, infections, and whether there is a history of adverse pregnancies or other high-risk factors. These factors may increase the risk of cerebral palsy in the fetus. Identifying and managing these factors can help reduce the risk.

4. Monitoring fetal movement: Pregnant women should record the frequency and intensity of fetal movements daily. Normal fetal movement indicates good fetal condition in the uterus. If fetal movements become abnormally frequent or decrease, it may indicate fetal hypoxia in the uterus. Prompt management can reduce the risk of brain damage.

5. Conducting imaging examinations: During pregnancy, ultrasounds or magnetic resonance imaging (MRI) can be performed to observe whether there are any abnormalities in the fetal brain structure, such as hydrocephalus or poor brain development. These abnormalities may be associated with cerebral palsy and can provide imaging support for early detection or exclusion of problems.

Strictly follow your doctor's instructions during pregnancy, complete all examinations on schedule, and proactively inform your doctor about your health status and any abnormalities. If any abnormalities are detected during examinations, cooperate with further tests and treatment to minimize the risk of fetal cerebral palsy and ensure healthy fetal development.

What causes hydronephrosis and how is it treated?
Under normal circumstances, the main causes of hydronephrosis include uterine compression during pregnancy, habitual urine retention, ureteral stones, ureteral stricture, and obstruction at the ureteropelvic junction. Patients can choose appropriate management approaches such as general treatment, medication, or surgical intervention based on their specific conditions. In daily life, it is important to develop healthy urination habits, avoid holding urine, and undergo regular medical check-ups.

What should I do if I accidentally get pregnant?
Preliminary determination can be made using a urine pregnancy test strip. If the result is positive, further medical testing is required for confirmation. Pregnancy test strips are easy to use and provide quick preliminary information, but they cannot replace professional medical diagnosis. It is recommended to visit a正规 medical institution, such as a hospital's obstetrics and gynecology department or a maternal and child health care facility, to seek professional medical assistance.

What are the side effects of painless abortion?
Under normal circumstances, painless abortion—as a method of induced termination of pregnancy—may lead to side effects including bleeding, infection, uterine perforation, intrauterine adhesion, menstrual abnormalities, and others. Painless abortion should be performed at a正规 medical institution. After the procedure, it is important to follow medical advice for proper care, such as avoiding tub baths, abstaining from sexual intercourse for one month, and ensuring adequate rest and warmth, in order to reduce the risk of side effects.

What does it mean when there is too little amniotic fluid at seven months of pregnancy, and what should be done?
Low amniotic fluid at seven months of pregnancy may be caused by insufficient water intake, mild placental insufficiency, fetal urinary system developmental abnormalities, gestational hypertension, or gestational diabetes. It can usually be managed through general measures, medication, or other treatments. If any abnormalities occur, prompt medical attention is recommended. In daily life, pregnant women should ensure adequate hydration, maintain a balanced diet, and avoid fatigue.
