What's the latest you got a BFP?

[PoppySeed31]

I'm currently 11dpo and getting bfn. I know it's still early but I can't help but think I'm out this month after a CP last month and feeling a little disheartened.

I didn't test until 14 dpo and my first positive was faint! It was a cheapie but then I got a clear blue (not digital) and even that wasn't the thickest line!
I know some people get BFPs at 9dpo or similar but I would've thought most people don't have enough preggo hormone until closer to 13 dpo. Good luck!
