In general, fetal monitoring can be done once a week at 34 weeks of pregnancy under normal circumstances, or from the 28th to 30th week of pregnancy if there is a combination of other diseases during pregnancy. As we all know, throughout pregnancy, mothers should not only pay attention to their own health, but also pay attention to the safety of the fetus, and many maternity examinations should not be omitted, so that the fetus can not be detected at the first time when something untoward happens. For healthy mothers-to-be, they can go to the hospital for fetal heart monitoring when they are 34 weeks pregnant, but if they have high blood pressure, diabetes and other complications, they need to advance to 28 weeks. If there is an abnormality in the fetal heart monitoring, it may be caused by the pregnant woman’s diet, mood swings, fever, hyperthyroidism, medication, etc. In this case, the mother-to-be should take appropriate treatment measures according to the specific instructions of the doctor. At the same time, she should adjust her life and diet and control her emotions, etc. so that she can conceive a healthy and smart baby. The fetal heartbeat monitoring can determine whether the fetus is suffering from oxygen deficiency in the uterus, once the abnormality occurs, the mother-to-be must cooperate with the doctor and actively carry out conditioning and medical treatment.
