I made it to 12 dpo and just had to test, so I did this morning with my walmart-brand early response and got a bfn.

Yeah.... I know I'm a few days before my period is due, but the test was completely white in the testing section, no hint of a shadow of a line. SO now I get to look forward to AF in the next 2-4 days.
Just disappointed I guess. We can always try again next time, its just with PCOS who knows when next time will be.
