Implantation bleeding??

Is it possible to have implantation bleeding right after my period? I started my period May 31st so this will be day 6. Everything has been somewhat like a normal period but yesterday I had some brown bleeding similar to the end of my cycle so I thought it was over but now today I’m having reddish/brown-like slimy discharge. It isn’t heavy but I do see it when I wipe. What could this be?
