What are my chances??

I took the test in the picture 9 dpo and got a faint positive. I took 3 that night and all had a faint but visible line, and all dried with dark evaps (though not putting stock into that, I just never get dark lines on my negatives even days old) I assumed this was my BFP!

I took one the next morning and it was negative, but chalked it up to difference in urine concentration. Tested the next day (11dpo) and another BFN. One more test yesterday night at 13 dpo and it was a stark white BFN.

AF is due tomorrow so I am waiting until I am officially late to test again. Has this ever happened to any of you and resulted in a pregnancy?? Hoping it wasn't a chemical or false positive but I feel like my chances are slim :/ What do you ladies think?
