If you do decide to go the "three month at a time" route, you don't need to switch to Seasonale/Seasonique to do so. You can just stack! (Don't take the placebos and instead open up the new pack.) Though, depending on your insurance plan, you may run into issues where the pharmacist won't give you your pills because it's not "time" yet. I don't know how to ameliorate this besides have your doc write the prescription to reflect how you take your hbc.
