I was on a 3 month on, 1 month break cycle of the pill for my endo and cyst.* Other than seemingly turning off all emotions, and some spotting the further through I got, it seemed to be fine.* I know I certainly appreciated not having pain as often as every month.As for the actual period, it suprisingly doesn't seem to make it heavier or anything (which I thought it would given the additional 'build up' time).
