GEM, I just wanted to add my {{HUGS}} and prayers for you during this most difficult time. I have been there too and know the raw emotions you are feeling. From the moment the pregnancy test comes back positive the love begins, and I am sorry your doctor was so incensitive to your feelings. You are not a failure, because you did nothing to cause your current condition, I know there are a lot of "what if I did this or what if I did that", but it simply was nothing you did. However, from reading some of the other posts here it looks like there could be hope, don't give up the hope and we will all think good thoughts for you.
In the event the worst does become a reality, allow yourself to grieve and ignore the ignorant people who sometimes say hurtful things (simply because they don't know). When I lost my baby I grieved like I lost my best friend for a very long time, people didn't understand and they were cruel because they would say it isn't like there ever was a baby it was just a bunch of cells and I should just get over it. This was hurtful because I was emotionally connected to this child, and yes empty sack or deformed fetus, to me and my husband there was a child.
As far as treatment in my case, the doctor sent me home to wait it out and I miscarried completely on my own a day or two after I started bleeding, so no other procedure was necessary.
You are in my thoughts and prayers, I pray for the best for you and your baby.
