Implantation bleeding

Did someone get implantation bleeding before BFp?! If so, can you tell me how was it? How long it lasted, color, consistency, and how long after that dos you get your bfp? Thank you so much for this, I've been spitting for 3 days just a little bit with cramps a week before af, 7,8 & 9 dpo which is absolutely rare, I never ever get spotting before af, thank you for reading this!!
