Implantation bleeding?

My period is 8 or 9 days late, and today I started bleeding a bit. Literally maybe 30 minutes ago. I put a tampon in, took it out a bit ago and theres already like brownish/pinkish blood on it but not a lot like I'm bleeding steadily.

My period always starts on a Saturday, in the morning. Never on a Tuesday night. I'm ttc so I'm hoping its implantation, but any tests I've taken have been negative.
