Implantation bleeding


Can implantation bleeding be red? And what’s it like? Is it just spotting? And how long does it last? My period doesn’t start until Tuesday but I’ve been bleeding off and on today. No cramping, just a reddish color. I have on a pad and it’s not showing up much on there but when I go to the bathroom it shows up more in the toilet. But it’s not like how my period usually is. So I’m confused.
