Fetal heart rate refers to the heart rate of the fetus, which can be heard by the doctor with a fetal heart rate monitor during the examination, and it is inaccurate and unscientific to determine the boy or girl from the speed of the fetal heart rate. Normal fetal heart rate is between 110-160 beats per minute, if it is lower than 110 beats or higher than 160 beats, it belongs to the abnormal range. If the fetal heart rate is lower than 110 or higher than 160, it is not normal, which suggests that the fetus may have intrauterine hypoxia, and it is necessary to do fetal heart rate monitoring and ultrasound to find out the reason why the fetal heart rate is too fast or too slow, and then give the appropriate treatment. During pregnancy, you should pay attention to diet, strengthen nutrition, eat more protein-rich foods, such as lean meat, eggs, milk, tofu, fish, shrimp, etc. You also need to eat some fresh fruits and vegetables, which is conducive to fetal growth and development. Pay attention to the movement of the fetus, and go to the hospital in time when you find that the movement of the fetus is too much or too little compared to the past.
