Chemical??

Re

I got my first bfp on 10/10. I had a beta collect that day and it was 10. 48 hrs later it was 23. I began heavily bleeding 2 days after my second beta (like super tampons) on 10/14 (4w4d) and it last about 3 days. I don’t have any other symptoms. Im assuming chemical. I plan to call and get my betas drawn again but I was wondering if y’all had any ideas why my test continue to get darker.
