I think whenever you're late there's always the possibility of pregnancy, even with the pill or injections or whatever. None of them are 100% for what I understand. I have been very late before because of stress, but by very late I mean about a week...the only times I've ever gone past a week late was when I was pregnant.
I'd take another test in a few days just to see.
