The appearance of fetal heart and buds does not mean that the fetus is completely safe, and pregnant women should undergo regular obstetric examination to ensure the healthy development of the fetus. Generally, fetal buds are formed on 40-50 days and fetal heart can be formed on 50-60 days of pregnancy. By detecting the fetal heart and buds, we can understand the development of the fetus in the uterus. So normally, pregnant women will detect the fetal heart and buds after the 6th week of pregnancy. However, since the fetus is not yet formed in the first 3 months of pregnancy and the fetus is in an unstable state, detecting the fetal heart and buds doesn’t mean that the fetus is in a safe state, and there is still a possibility of fetal ejection. Therefore, it is necessary to test the fetal heart and buds throughout the pregnancy. In early pregnancy, you need to pay attention to the presence of fetal heartbeat and buds; in mid-pregnancy, you can monitor the frequency of fetal heartbeat, and the normal fetal heartbeat should be 120-160 beats per minute; in late pregnancy, in addition to paying attention to the fetal heartbeat, pregnant women also need to count the movement of the fetus by themselves, and if the fetus is abnormal or even intrauterine death, the heartbeat will disappear only after the movement of the fetus has disappeared. To summarize, in early pregnancy, we should pay more attention to rest, relax, maintain a good state of life, avoid overwork and strenuous activities. You also need to pay attention to timely supplementation of folic acid to prevent fetal malformation and other conditions. Normally, you can eat fruits or vegetables to supplement the vitamins needed by the body, and carry out obstetric examination regularly to ensure that the development of the fetus’s body is in good condition.
