Being about five months pregnant generally corresponds to around twenty weeks of pregnancy. During this period, if premature rupture of membranes (PROM) occurs, fetal movements are usually still perceptible. This is because, although amniotic fluid intermittently leaks due to PROM, it continues to be produced. Therefore, a certain amount of amniotic fluid remains within the amniotic cavity, providing space for fetal activity, allowing the mother to feel fetal movements. However, sometimes there may be abnormal changes in fetal movements, such as an increase or decrease. For a five-month pregnancy with PROM, regardless of the presence of fetal movements, it is generally not recommended to attempt to preserve the pregnancy. This is because the success rate of sustaining the pregnancy is very low at this stage. Even if the pregnancy could be extended by about a month to reach twenty-four weeks, the survival rate of the fetus remains extremely low. Therefore, when PROM occurs at five months of pregnancy, although fetal movements can still be detected, it is not possible to maintain the pregnancy, and it is necessary to promptly opt for induction of labor to terminate the pregnancy.
