Thanks to you both for the info you have given me. I had a retained placenta for my first, I was induced at 39 weeks due to at the time thru ultrasound they said I had a large hemetoma on the placenta. I lost about 800ml that time and took 3 mths to recover due to low iron. For my 2nd, they looked at placenta accreta due to lakes etc at ultrasound and monitered me for babies growth, unfortunately the MRI that was meant to have been booked was not due to my doctor going on holidays and the replacement one (public) got mad at me because I refused to be induced at 37weeks. So he did not book it, my midwife stood by me though and knew the details. I went into labour naturally at 39wks3days, birth went great, 6 hrs only shower for relief, just what I wanted. Unfortunately I started hemorraging straight away, when they tried to get the placenta out the cord broke off and well rushed to theatre, lost 2 litres of blood. 4 transfusions later all was ok though.
Now with this one, lakes discovered at 19 week scan, MRI booked for 34weeks. I have been given some info (mainly my midwife) the doctor is good but admits she has not seen many cases as it is rare. Suppose I will just have to wait and see. If I need a hysterectomy, Im ok with that, just wish there was more info available
