Help please! So frustrated! :(

I'm 6 DPO and went to check my cervix..because well let's admit we're all crazy TTC! Haha) and I had a bunch of white CM on my finger and also a tinge of blood. I checked it a few more times and it was still there, very faint. 😔 AF isn't due til the 15th so I still have a week. I normally spot 2-3 days before my period...maybe implantation bleeding? But I've heard that's rare...AF is prolly on her way...month 4 of TTC #2...feeling so frustrated and defeated...
