miscarriage

So last Thursday, I had very light spotting. And then progressively, the bleeding became severe with lots of clotting. I'm still bleeding heavily and yesterday I bled through a tampon. It's August 24th right now and I was due for my period around September 1st, but only because I had a late period last month due to stres. I think this could be a miscarriage because of the cramping and how it got progressively worse. I'm still bleeding now and if this was my period, it would be ending tomorrow but it's showing no sign of ending. Please help me !!
