I always skip the green pills, or "sugar pills", however I never start a new pack immediately. I always give my body a rest from the pills and have a period. The only reason I don't take the placebo pills is b/c I have been taking bc for the past 4 years, so I'm in a pretty good habit of knowing when to take them. I do the Sunday start, so I know the Sunday after my period has started I that I need to start a new pack. This works great for me, because my period usually lasts from Tue-Sun/Mon. In essence, on the hills of my period ending, I start a new pack. I keep it simple when it comes to BC. I'm not trying to risk starting a pack right after finishing a pack. I just believe that's there something good about letting your body "go natural" for a week.
