I don't really know what to expect; I've been spotting for 2 weeks now but Sat and Sun I had a few hours of heavier bleeding and mild cramps, and that's happening again now. Is this it? Or is there more eventually? The doctor totally freaked me out and said it would be worse than labor but this is just like a period.

I went through the same thing with the spotting that got heavier. Depending on how far you are, there will be no question of when you have actuall miscarried. It was worse than a period, and for me I had rhythmic "contractions" for about an hour before I passed a large clot. I had previously experienced smaller clots, but this one was pretty large and unmistakeable. Once it was gone, the pain went away immediatly.
I hope that helps. I guess my best advice is that you will know when it happens, there won't be a question. Also, as far as a timeline, I think it took me about 2 weeks of bleeding before it actually happened.
I pray that everything go smoothly for you, and am so sorry for your loss.
