You're overthinking this, using the same kind of thinking that makes you anxious in the first place. Obviously two minutes doesn't matter an iota. And the directions for what to do are in the packet that comes with the med -- what to do if you miss a dose. But two minutes or two hours isn't missing a dose.
your ok just try to take it around the time you always do and use a pill case cuz I have 15 prescriptions and I'm never late
