Implantation bleeding or super early period?

KW

Just wiped blood after peeing....my period isn’t due to start for another 6 days. Not sure if there’s a way to tell the difference, from what I’ve read implantation bleeding is really light so it’s hard to tell right off the bat. I haven’t had an early period before but I also didn’t have any implantation bleeding with my first pregnancy soooo I guess the only answer is to wait it out?
