Premature rupture of membranes refers to the rupture of the amniotic sac before labor, causing intermittent discharge of amniotic fluid. Premature rupture of membranes can occur at any stage of pregnancy, and it is generally believed in clinical practice that it is more likely to occur in the mid to late stages of pregnancy. The probability of occurrence before 20 weeks of pregnancy is relatively low. If premature rupture of membranes occurs at 14 weeks of pregnancy, once diagnosed, it is irreversible as there is currently no method to cure it. For 14-week premature rupture of membranes, an ultrasound, vaginal examination, and pH paper test should first be conducted to confirm whether it is indeed a premature rupture of membranes. If it is confirmed as a premature rupture of membranes, then the only option is to terminate the pregnancy; if it is not, the pregnancy can be continued.
