I am on ortho-tri cyclin, or rather the generic version of it, and I was wondering about my cyle. My period always starts 4 days after the active (blue) pills stop, so by the time it's done it has been about 11 days since the active pills instead of 7. Am I supposed to start taking the active pills after 7 days even if im in the middle of my period or do I simply start again when my period's done for the pill to be effective. I've been waiting so please let me know soon so I know if i'm wrong. Thanks!
