I had a friend in hospital with me last year that had very bad placenta accreta and as that was her last bub she had a c-section at 37 weeks (only made it that far on bed rest) and requested they take her uterus out at the same time as the placenta had grown right through her uterus and onto her bladder.
I hope its an easier run for u than what she had as it was no fun for the poor lady with 6 kids at home and being stuck in hospital an hour away from home
