Generally, the earliest fetal heartbeat can be heard at about 12 weeks of pregnancy, but there are individual differences.
Hearing the fetal heart sound can confirm the diagnosis of live birth, generally the earliest can be about 12 weeks of pregnancy with Doppler fetal cardiograph can hear the fetal heart sound, like a clock ticking, the speed is relatively fast, the normal 110 ~ 160 times per minute, pay attention to the fetal heart sound and uterine murmur, abdominal aortic sound and umbilical cord murmur of the differentiation.
However, for pregnant women with thicker abdominal walls may delay the time when the fetal heartbeat is heard by the fetal heart monitor.
Fetal movement should also be monitored during pregnancy, and it is generally recognized at about 20 weeks of gestation, and after 28 weeks of gestation, it is necessary to follow the doctor’s instructions to measure the fetal movement, and it is ≥ 10 times/2 hours, which is the easiest way for pregnant women to self-evaluate the condition of the fetus in the uterus.
When the fetal movement count <10 times in 2 hours or the overall reduction of 50%, there may be a risk of fetal hypoxia, we should go to the hospital to avoid delay.
