Diagnosed with placenta previa at my 32-week scan. is there still a chance that the placenta will migrate? im praying for a natural birth but want to be practical as well.

Unlikely: If diagnosed in early pregnancy, a placenta previa has a chance to resolve on its own. Diagnosed at 32 weeks, it is most likely fixed and you will need a C section to prevent life threatening bleeding. Although not "natural", a C-section has many benefits for the baby including less skull deformation, and fewer birth injuries such as asphyxia, shoulder dystocia and fractures.
