I Had My Period And It Ended On The 12th

I had my period and it ended on the 12th it only lasted 2.5 days. I had really bad cramps and bloating prior to starting it. On the 20th of this month a week later I started spotting blood and I am continuing to bleed lightly or brown and this is day 4. I have some cramping today and I am gassy. I also have a bleeding disorder, but this has never happened prior.
