implantation bleeding?

Sorry idk how to do the TMI on pictures!! This is really really thick....possible conception last Sunday, too early to test, i had a period on 7/20 went off BC pills and had one 8/9 again so i shouldnt be bleeding...its fairly light, started this morning with just a few spots, then this. I cant even feel it and it hasn't even gone through a pad in four hours. Like a liner would be enough.
