I am so very sorry to hear of your loss. No words will make that better.
When i had my first MC I was only 4 weeks but I had excruitiating (sp?) pain horrible horrible cramps poor dh did not know what to do whether or not he should take me to the hospital etc - so yes I guess this can be normal. As for the bleeding everyone is different but it can take a while. It is good that you are going to the Dr though just to be sure everything is ok - they will be able to give you the advice and support you may need.
they may even offer you a curette, I wish I had taken this offer when it was given to me at the time, as I believe it didnt help me hold onto the second baby either. but that is just my opinion. You will cease bleeding completely with a curette too.
If you need someone to talk to feel free to PM me.
