I know having your period is reassurance that things are working correctly, but don't forget, things actually *aren't* working correctly when you're on the pill. When you take the 1-week break from the active pills you're actually artificially causing your period. The people who first invented birth control pills actually thought that women would "miss" having their periods every month (ha ha) - plus it would be reassurance that they weren't pregnant - which is why they designed the pill to have the break every month. I guess my point is that missing a pill period probably doesn't mean much because your system is not operating normally on the pill in the first place. If it bothers you, though, then switch by all means.
