TMI ! NEED ADVICE ! PLEASE !

AF Is due in 2 days. (12/2) I have had ZERO period symptoms! I've had this kind of discharge all day. Sometimes a little more and little darker. And very slight weird cramping. But nothing that feels like period cramping. I NEVER get this. And if I do it's the same day as my period and literally I'll see this then boom bright red and it's AF. But not even a little red or pink has been on my toilet paper. Could this be implantation? If so should I wait til my maybe missed period to test ?! I don't wanna get my hopes up but if this means I'm pregnant I seriously don't want anything else for Christmas! Thanks in advance!
