How many weeks can complete placenta previa be guaranteed

Complete placenta previa can last up to 37 weeks.

If the amount of bleeding is small and can be controlled by bed rest and medication, the fetus may continue to develop in utero. However, if the amount of bleeding is large, it may cause problems such as hypoxia and distress, increasing the risk of premature delivery. The mother's physical condition can also affect the effect of pregnancy protection. If the mother has other health problems, such as hypertension and diabetes, it may increase the difficulty of pregnancy protection. In the process of pregnancy preservation, doctors may take a series of medical interventions, such as bed rest, the use of contraction inhibitors, blood transfusions, etc., to ensure the safety of pregnant women and fetuses.
