I take an active birth control pill every day of the year and never have a "period" at all. When your on the pill it is not really a period anyway, but rather withdrawl bleeding from the removal of estrogen. I take pills that way to avoid headaches, because I'm early stages of osteoporosis and to try to lower my risk of ovarian cancer (which my mother has). I love it - have done it this way for two years. The pills I take are Kariva (generic of Mircette) I only take the active and not the off week ones. I don't have UC, though.
