If I go off birth control for 2 weeks and then go back on it but on another brand, how does that effect my coverage or protection against pregnancy?

Decreased protection. The question essentially asks if protection against pregnancy is increased, unchanged, or decreased, if a woman skips 2 weeks of birth control pills before starting a new pack of pills (in this case, a new pack of a different brand). The answer is "decreased" protection. Therefore, she should use condoms or another second form of birth control during that one new pack of pills.
