BFN at 12dpo, is there still chance for a BFP

Samantha • Mom of a beautiful 2 year old, Emmy. Trying to conceive miracle #2, TTC for a year so far with PCOS.
Has anyone gotten a BFN at or around 12dpo and then gotten a BFP later? I really am having a hard time accepting I am out this month at 12dpo!
