My most recent miscarriage took a while (I have had 3). My bleeding started at 10 weeks when the pregnancy failed at 6. I bled for two weeks then had terrible cramps in the evenings for three days in a row. The third night I had to call my husband home from work to take care of our daughter and I miscarried 30 minutes later. The pain at that point was very different than passing a clot. Since the sac was still growing what I passed was 3 inches long and about 1 inch wide. As soon as the miscarriage was done it was instantaneous relief.
Most likely you have not yet miscarried, your body is just preparing.
Either way, call your doctor whenever you have questions. They should be supportive through this process and if not, find another doctor. My doctor gave me his cell phone to call whenever needed.
Also, if you do pass something different than a clot (you will know) save it and bring it to your doctor. The pathologist can make sure you passed everything and if there is a fetus you can request it is tested for chromosome abnormalities.
