Hello
As with everyone else - goes without saying that I'm sorry for your loss.
I have had two ERPC after 12 week scans - I personally was more frightened of the anaesthetic rather than anything else - but you are under for such a short amount of time. I would definitely recommend - personally I couldn't have waited - and just wanted to "get on with things" ie trying again. The bleeding afterwards really wasn't too bad either.
My second one turned out to be a molar pregnancy which was far more boring as you can't get pregnant again for 6 months +.
Good luck with whatever you decide
