Placenta accretia??

Anyone had/have placenta accretia? I'm a repeat c section; currently 20w4d. I've had 2 cesareans and will be having a third in may. I learned last week when I kept feeling baby girl move less and less that my placenta had moved from being over my cervix, to now being in the front near my previous cesarean scars. It's preventing me from feeling her most of the time. I'm worried about the bleeding risk and things if my placenta grows into my scar as I've that's what I've been reading everywhere.
