Can i weak cervix cause a miscarriage?

Yes, a weakened cervix, often referred to as cervical insufficiency, can lead to miscarriage or preterm birth. In this condition, the cervix may open too early during pregnancy, which can result in the loss of the pregnancy, typically in the second trimester. Women with a history of cervical insufficiency may be monitored closely and may require interventions such as a cervical cerclage to help support the pregnancy.
