Fetal movement like a heartbeat is how to return a responsibility

Fetal movement and heartbeat are generally the performance of fetal hiccups, generally mild, but the duration is longer than the general fetal movement, this is the performance of the fetus swallowing amniotic fluid in the uterus. If only occasionally a fetal hiccup occurs, it is normal, do not worry, if frequent hiccups may be caused by hypoxia.
