Chemical or still pregnant?

Kelly

So on 12dpo I got a positive FRER and a positive digital. On 15 dpo I started spotting, and then heavy bleeding with clots a few days later. I still have positive pregnancy tests every day.

I had a chemical in October, and when I retested on 16dpo it came back negative. I am confused as to why the tests keep coming back positive, even though I am bleeding. I am going to try to make a doctors appointment for tomorrow to get my levels checked, but thought I would ask on here first to see if anyone has any ideas/experience with this.

12 dpo positive tests

Positive tests since bleeding started on 15 dpo.
