Bleeding and crampin 10 days after miscarriage?

Maria
I started spotting around July 24th and miscarried on August 6th. I spotted for a week and then nothing on Sunday or Monday.  Today Tuesday afternoon I got terrible cramps and started bleeding.  Is it possible to have a period 10 days after a miscarriage?
I also have large fibroids and my periods are generally heavy lengthy  and painful.  Cycles are 34 to 36 days long.
Anyone experience a period so soon after miscarriage?
