Chemical... again?

Y’all. I’m trying not to freak out.

11 DPO I tested and it was negative, Stark white.

12 DPO (yesterday) I tested twice and got positives (2 different brands of tests)

13 DPO (today) I tested (see picture posted here) but I’m bleeding.

With my last chemical I had positive tests for two weeks started at 12 DPO and THEN I bled. I just don’t understand what’s going on. And of course my doctor doesn’t work on Mondays.

Has anyone ever bled heavily and still been pregnant?
