Implanation diarrhea????

So I'm right around the time of possible implanation. Had to get out of bed this morning for such bad cramps and had diarrhea several times with a bit of spotting. Has anyone had diarrhea st implanation? Or is it just af as I first thought just showing up a few days early. I also took imodium for the diarrhea before glueing into think may be it was implanation... Does anything one think that will make a difference?
