If you were five days late for your period, it seems like the pregnancy test would be accurate. Maybe you had an ovarian cyst this month that made your period odd. I don't think it would be implantation bleeding if you were 5 days late for your period; that would be the wrong time in relation to ovulation.
The bloody mucous that you describe may have been a miscarriage. Did you have a pregnancy test done before your implantation? If you did miscarry, your pregnancy test afterwards would be negative.
