Generally speaking, there is no time requirement for fetal heart monitoring, but in some cases, the fetal heart may slow down in the afternoon due to sleeping, etc. Therefore, it may be better for pregnant women to choose the morning for fetal heart monitoring.
Fetal heart rate monitoring refers to placing a probe on the abdomen of a pregnant woman to listen to the fetal heart, through the machine to depict the changes of the fetal heart over a period of time, according to which to comprehensively determine whether there is a lack of oxygen in the fetus in the uterus. Fetal heart monitoring usually has no time requirements, so pregnant women can go for it in the morning or in the afternoon.
However, some fetuses may have a slow heartbeat in the afternoon due to sleeping, resulting in relatively inaccurate results. Therefore, it is generally better to choose to do the fetal heart monitoring in the morning.
Pregnant women are advised not to be too anxious when going for fetal heart monitoring, to relax and to report any abnormalities to the doctor in time.
