Chele - THere is always a chance your placenta will move, I really hope it does for you. My neice`s placenta was exactly same position as yours but she was having regular checks due to the PP and a stitch in her cervix, her placenta did eventually move but it wasn`t until she had the 32 week ultrasound, she went on to labour her baby.

Good luck to you I hope it all works out well
