Period or miscarriage???

So I was suppose to start my period on the 15th. Didn't start til the 26th I was having crazy dreams and wanting crazy things very emotional and moody. But when I started on the 26th it was heavy like a miscarriage and very very dark the cramps is damn near unbearable... Is this just real bad cramps or a miscarriage? I had two miscarriages before, 1 at 5 weeks and 1 at 8 weeks where I had to get a DNC done. And still never felt pain like this. HELP PLEASE
