Earliest BFP you've gotten

Kelsey • Mommy to a beautiful 5 year old little girl and handsome 3 year old little boy. Another sweet Baby boy coming in May!
Im 7DPO and 9 days until AF is due. I'm really hoping this is our month and honestly I've already taken a test (totally crazy I know). I thought I saw the faintest line and some people said they saw it on here also. Although, I'm starting to think it must have been an Evap. My question is what's the earliest BFP you've gotten?
