I am so so sorry for your loss, I feel like crying for you, this is wholly terrible. From miscarriages the liver looking stuff is placenta.
I'm shocked they gave you no warning, no support, a botched procedure, a conveyor belt approach for something that was a very intimate and distressing time.
I would guess that so soon MS would say oh it's the emotional impact. So I would suggest you write as much as you can down, from initial examination/consult with them, till the end.
It sounds strongly as if you were having doubts, but seeing as this would hold up the conveyor belt, they rushed ahead without properly consulting you. If you can recall, I know emotionally this will be painful, but jot down had scan, had prick test, were you consulted after the scan if you intended to proceed? How long a gap was there between scan and sedation?
A relative had an abortion that would be determined an ERPC, the scans were first to confirm dates, then a further one before procedure, the day before I think. To go over pre-op, counselling and so forth. So I believe from what I vaguely know there were time steps that allowed you to say, hang on I'm not sure.
Note that you were in distress. Note everything you can after, retained products, infection from IUD plus ectopic pregnancy which could have been life threatening. Obtain clinical notes from the hospital to support all this.
Then when it's not as raw, as I fear you may still require further intervention, although I was told by scan everything was passed, but I continued to pass the liver like stuff for 2 weeks, at 3 weeks the baby was passed. So please feel free to say you know someone who was told all was clear, but continued to pass the liver like stuff, with heavy, painful bleeding. What do they suggest? What are your HCG levels now?
I'm really sorry you're having to go through this.
I honestly feel sickened by the way you were treated by MS.
