Implantation bleeding? (Possibly TMI, no pictures)

So, since Friday afternoon (it’s now Sunday) I have had a very small amount of bleeding. I normally have very heavy periods, but this has been very light. Only filling the tips (like half an inch) of 3 tampons. It’s more brown instead of red, but it does have red bits. It’s definitely a different color and lighter than my normal periods. Could this be implantation bleeding?? I hope so, but I know it’s too early to test! I read test a minimum of 2-3 days after implantation bleeding. I’m getting restless. Any hope?

Also, my periods have been a few days to a week late the past few months, but this was 2 days early...
