Miscarriage or period?

So I started miscarrying about 5 weeks ago after 12 weeks of a missed miscarriage. A week later I had the worse pain ever and I believe that is when I was finally passing the pregnancy. I have continued to bleeding non stop since then with the flow becoming super light with just staining the toilet paper. Today I felt wetness and when I wiped I saw a clump and the blood was a bit heavier and bright red. I think its my period returning but I am not sure since I never stopped bleeding and Ive had days when its lighter than others. Im super off track.
