1. Premature rupture of membranes Premature rupture of membranes before uterine contraction is called premature rupture of membranes. After the fetal membranes rupture, the inside of the uterus is in direct contact with the outside world, and intrauterine infection may occur. If there are no uterine contractions and rupture of membranes at term or labor, pregnant women may worry about premature rupture of membranes leading to the loss of amniotic fluid. If uterine contractions do not have the buffering effect of amniotic fluid, will the fetus be in danger? In fact, amniotic fluid is continuously produced. Amniotic fluid is secreted by fetal membranes, the fetus urinates, and the fetus swallows amniotic fluid.
