Period came July 27.2015

Left August 2.2015

On August 5.2015 at 327pm I started bleeding. When I use the bathroom small clots came down. Then it was light bleeding all afternoon to night 

On August 6.2015 still light bleeding until 827pm I bleeded heavy with three median blood clots and still bleeding until I don't know when. 

Please help if anyone know was going on this first time it happened
