bubble I really feel for you. The medical stuff was, for me, the most distressing part. I didn't find my EPU to be particularly helpful or organised, but hopefully yours is better!
I had to go to the hospital three times during the week of my miscarriage. I had one internal exam a couple of days into the mc, an internal scan two days later and a blood test every other day to measure HCG levels, check for ectopic pg etc. I had to go back each week for a fortnight to check that my HCG levels were dropping, until they reached 0.
I'm not sure how long bleeding usually lasts- I think it really varies. Mine lasted for a week, with a peak (when I passed the "products"- sorry I know it's horrid to mention) on the third day of heavy bleeding. But every mc is different.
Basically if the pregnancy is definitely over, your HCG levels should drop by half each day. The EPU should be able to give you your levels when they do a blood test- I noted mine in my diary as it helped me to see that the levels were dropping as they should be- I also found it useful as I knew that I would get a positive hpt if I did one, so seeing the levels written down stopped me from getting my hopes up (funny/mad how the mind works).
Anyway sorry to go on- I just know that I found the experiences of women on this forum to be helpful when I was having a mc, so I hope this will be useful to you too.
