i am so sorry to hear you are going through this. from what you are describing, you are having a molar pregnancy (did your doctor use sth similar to call your condition)? it is good that they spotted the process, it happens very rarely but if they spot it in time, it can all go well in the end.
losing blood can happen as you probably needed a more extensive D&C to make sure that all the bad cells are gone (better lose some more blood now than leave some of those cells in there, as they could potentially develop into cancer cells). it will all set in, they will keep you checked up for another 6 months regularly and it will all be ok.
this is a major trauma you're going through, so i hope your docs are smart enough to refer you to a therapist/psychologist/someone trusted you can talk to outside of your family. if they don't, then ask for it. it is your right and it could really help you in the long run.
hugs!
