Implantation bleeding ??

Nia

So we’ve done it on all the right days and then some. Today I’m on cd 26 and my period is due on cd 28. I’ve been having some colored discharge since cd 24.

This is how the discharge looked today(cd26) about 12dpo( 12 days after positive opk as well) On cd 24 it was more of an orange kind of color. Could this be implantation bleeding ?? I took a test today and got a bfn. Also, I seen some spotting like this last month and my period ended up coming. I normally don’t spot at all before periods, this is the second time. I’m thinking my period is just gonna come like it did last month..
