I'm on ortho tri cyclen lo 21 day birth control, there are no placebo pills.. The package says to take a 7 day break, so I would've taken the new pack on Sunday but I instead started it today (Saturday) would this change the effectiveness of the pill? Or elongate my period?
Please help!
& thank you in advance

Would I take a chance? No. I would also use an alternate form of birth control for at least one cycle.
