My brother, who is a physician, just informed me about the daughter of a colleague. She went in for her 3rd delivery, a c-section, had placenta accreta and amniotic fluid embolism and is now in critical condition in the intensive care unit. I had never heard of this and have only been able to find minimal information on the internet search engines.
It does look as if I have some of the risk factors however,
AMA - advanced maternal age
previous c-section
