Placenta Previa at 30 Weeks

Hi mga mommies! First pregnancy at 30 weeks. I had my first UTZ po at my 25th week to check my baby’s gender, it says my placenta is Anterior Grade 2 - High Lying (still breech). But just yesterday, at my 30th week & 2 days, I had my UTZ po ulit, now my baby is at cephalic presentation already but my placenta is Anterior Grade 2 - Totally Covering the OS daw po, meaning I have Placenta Previa. ? pero NO BLEEDING at all po ako. May chance pa po kaya na magbago pa position ng placenta ko? What can I do po aside from bedrest? ??
