What’s the latest you got a positive or BFP?

Zoe

I’m currently 12 dpo (my period is supposed to be here tomorrow). I took a test this morning it looked to be negative with the SLIGHTEST hint of a line (pretty much nothing there) so I’m wondering when’s the latest any of y’all got a positive or BFP because I really feel like I could be pregnant. My symptoms are different than my average period and I don’t want to lose hope just yet.
