What’s going on?

Ok so for 3 days I been spotting really light pink I didn’t need a pad I only see it when I wipe. Yesterday I had a so called period It was red but I did need a pad but it’s not heavy like my normal period is and didn’t really fill up the pad. Today I’m barely seeing any blood on my pad just spotting a lil bit, but now I see it when I wipe. My “actual” period was suppose to show on the 10th. So is this my actual period or implantation bleeding? I read implantation bleeding can be red it all depends on the person body. What do you think?
