Hello.... You are already taking ginette.. It acts as oral contraceptive if taken regularly, so no need to take another pill... Stopping ginette causes profuse bleeding... Cyproteron actate is derivative of progesterone which is there in ginnete.. On missing one pill, the missed Pill must be taken within 12 hours, even if it means having to take two pills at the same time on the next day. Continue the remainder of the pack as usual.
