Anyone have this after a miscarriage?

My periods are always on time and last about 5 or 6 days. This month it started normal but on the 3rd day it completely stopped. Well until that night, then it was very light. Then yesterday it stopped again, every now and then there would be a few brownish drops but that's it. Now today, halfway through the day its back to being red blood, not heavy but not very light either. I did just have a miscarriage last month, and I've also started taking prental vitamins so I was wondering if either of these could be causing it to be weird this month??
