I think I'm having implantation bleeding?

I had one spotting sat night. Brown, light when I wiped. 2-3 spottings on Sun. Then one this morning. So I'm still in the 48 hour period I guess. None of the spottings have been red or heavy. I've never watched my discharge so much in my life. I'm supposed to have AF on this coming sat. Fingers crossed that it is IB and not an early AF. Please ♡ Gonna be a long week
