Premature rupture of membranes leading to miscarriage and then preparing for pregnancy requires general preconception tests such as vaginal discharge test, gynecological examination, infectious disease test, eugenic quadruple test, ultrasonography, etc., but after pregnancy, it is important to pay attention to the management of pregnancy. Premature rupture of membranes leading to miscarriage may be due to reproductive tract infections, increased pressure in the amniotic cavity, uneven stress on the membranes, trauma and nutrient deficiencies. There is no need to check anything special before getting pregnant, just do the routine pre-pregnancy checkups. However, pregnant women with preterm rupture of membranes have an increased likelihood of preterm rupture of membranes when they become pregnant again, so they should pay attention to the management of their pregnancy. Pay attention to personal hygiene during pregnancy and treat any reproductive tract infections as early as possible. Ensure balanced nutrition during pregnancy, as well as rest and avoid heavy physical activities. Pay attention to personal safety and avoid trauma. Pay attention to regular obstetric examination during pregnancy, and if there is laxity of the endocervix, cervical cerclage is needed.
