Low lying placenta / Subchorionic Hemorrhage

Hello po. Ask ko lng po if possible bng mag move upward ung inunan (placenta) ni baby at mawala ung subcho.hemorrhage? I am currently 14 weeks preggy first time mom. As of now, pinag bed rest ako ng OB ko and niresetahan nya ako ng Progesterone 200 mg orally taken every 12 hours. On and off pa rin kasi ung spotting ko until now. Di naman siya bright red, more on brownish red siya. Sana po may makasagot. Thank u.
