Implantation bleeding?

Yesterday night I started bleeding my period isn’t do for another 6-8 days my last period started may 13 th and my periods are usually 7-8 days long , the blood wasn’t bright red or heavy it did seem like possibly spotting and was more of a light red pinkish Color then when the bleeding stopped( I wore a pad overnight but no blood this morning just discharge so I believe I stopped bleeding at some point at night ) this morning there was discharge that was light brownish color and that’s been going on all day today I honestly don’t know what’s going on with my body but I’m thinking I might be pregnant and that what I went through was implantation bleeding Im kind of stumped on what it could be besides that because last time I thought it was implantation and it wasn’t I got my period the exact next day bright red .
