Back again. I didn't have much time to reply before. There was a concern I had a placental accreta with my 3rd baby. This was because of the appearance of the placenta at my 19week scan (multiple large lakes and very vessely) combined with my higher risk due to previous retained placenta with haemorrage and uterine surgery from this and removing adhesions in 2009 which were thought to be one of my causes of infertility. There was also concern with my 1st that the retained placenta was a mild accreta as it was very hard to remove under general and I bled further after it was eventually out.

Anyway what I did learn was it is extremely rare to be diagnosed before the birth. Almost all placenta accretas are not picked up until after birth when the placenta fails to be expelled. Of all the midwives I worked with a few had experience working with women who had one all in major hospitals in Sydney (the royal womens were one). The 2 midwives who had experience both said they commonly leave the placenta in the uterine wall (after removing the bulk of it) and usually the roots are eventually passed or reabsorbed so the uterus can be saved for future pregnancy if desired.

My ob said my greatest risk factor was 2 previous uterine surgeries. I ended up delivering vaginally just shy of 38weeks and my placenta came out within 10mins (active 3rd stage) They said it was a massive placenta but it was my most normal looking placenta so far (my 1st came out shreaded as it was a manual removal and my 2nd had 3 extra parts to it) I bled heavily for 2days but did not require any special treatment for that.
