Implantation bleeding typically occurs 7-10DPO
I had it at 7DPO, I wouldn't have known had I not checked my cervix. I forget now but it was either light pink or brown. As the others have said I had no preggy symptoms the cycle I fell preg. I had sorer than typical boobs when AF was due but not horrendously sore. The reason I tested was my BBs stopped hurting & I spotted still at 14DPO, my LP wasn't typically that long.
