Period after D&C?

Michelle

I had my D&C done Sept 25. Spotted for 5 days and then the night of the 5th day had a large amount of tissue/globs pass. After that I spotted for 5 more days. So by Oct 4th bleeding stopped. October 20th I started heavily spotting/very light bleeding brown for 4 days. Then nothing since. Could that have been my period?
