Implantation Bleeding or Period?

Taylor • ♡♡♡♡♡♡♡♡♡

Hey ladies. I have been off BC for 1 1/2years now and actively TTC for #2.

I had some cramping 9dpo which I'm hoping was implantation. And today 11dpo I was preforming a CM check and it had some pink/brown tinge along with cramping. I know that can be common during implantation. AF due in 3 days. Any chance its NOT my period?
