Im 5 months preggy. But low lying placenta. Anybody knows what to do about this?

I had placenta previa on my 5th month also. Completely covering the os pa. I'm on my final trimester now and high lying na ang placenta ko. What I did was: -Bed rest -Elevate my hips using 2 pillows for 30 mins - 3x a day. Medyo OA pero kasi gusto ko talaga mag normal delivery. -Duphaston 2x a day for 30 days.
