Chemical or miscarriage?

Okay so I'll try to make this as brief as possible. I miscarried last month at about 8 weeks. 3 weeks later I started having pregnancy symptoms so I decided to test. I took about 10 tests over the course of a week all were positives. Some dark some faint. I went to the doctor friday and the urine test I did there came back negative. I got blood drawn and will get results of that tomorrow. Yesterday I started bleeding. Light at first but today it's super heavy and I'm passing a good amount of clots none have been bigger than a nickel. So I guess what my question is could this be a chemical pregnancy or just a period? I know your first period after a miscarriage can be rough but doesn't explain all the positive pregnancy tests. Hate not knowing what's going on with my body.
