pcaneta previa

so my placenta is blocking my cervix and apparently it's anterior little ones healthy and kicking about but just wondering how likely my placenta is to move up I'm 22+5 my ultrasound was at 22+2 and if it doesn't move up around how many weeks pregnant will I have a c section my cervix is measuring at 37 so apparently that means no early labour which is good and did anyone have any do's or donts for this or any complications ? thank you for any replys 😙
