The appearance of fetal heartbeat and fetal bud does not mean that the fetus is completely safe, and pregnant women should have regular maternity checkups to ensure the healthy development of the fetus. Generally, fetal buds are formed in 40-50 days and fetal heart can be formed in 50-60 days of pregnancy. By detecting fetal heart and fetal buds, we can understand the development of the fetus in the womb. Therefore, in general, pregnant women will detect fetal heartbeat and fetal bud 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, the detection of fetal heartbeat and fetal bud does not mean that the fetus is in a safe state and there is still a possibility of fetal abortion. Therefore, the fetal heartbeat and fetal bud need to be tested throughout the pregnancy. In the early stage of pregnancy, we need to pay attention to the presence of fetal heartbeat and fetal bud; in the middle stage of pregnancy, we can monitor the frequency of fetal heartbeat, which should be 120-160 beats per minute; in the late stage of pregnancy, besides paying attention to fetal heartbeat, pregnant women also need to count fetal movement by themselves, if the fetus has abnormalities or even died in utero, the fetal heartbeat will disappear only after the fetal movement disappears. To sum up, in early pregnancy, we should pay more attention to rest, relax, maintain a good living condition and avoid overwork and strenuous activities. It is also necessary to pay attention to timely supplementation of folic acid to prevent fetal malformation and other conditions. You can eat fruits or vegetables to replenish the vitamins your body needs, and have regular maternity checkups to ensure that the fetus is developing well.
