Take it tomorrow and then resume your normal schedule: Wednesday next week.
Why? When you take your loading doses of Humira, you take a bunch of doses together with the goal of getting your blood concentration of Humira up to an ideal therapeutic (healing) level. Being a few days late is no big deal, assuming you take the missing dose and then resume the normal schedule. You shouldn't skip any doses (no missed doses).
