Would the bleeding that I had be spotting???

So last Monday I was due to start my period. And I did start bleeding on monday. But the bleeding was only there when I wiped and sometimes there would be tiny clots in it and it would never go on a pad. It did that the whole week last week. And now today it's actually going on a pad and there's some pieces of lining coming out. Would what I had last week be spotting then? And would today be the start of my period?
