After you finish your Crina NCR (norethisterone) course, you will typically experience a withdrawal bleed within a few days. You should start taking your Dronis 20 (drospirenone and ethinylestradiol) on the very first day of this bleeding, which marks Day 1 of your new menstrual cycle. Starting on Day 1 provides immediate contraceptive protection. If you start between Days 2 and 5 of your period, please use an additional barrier method like condoms for the first seven days. Please consult your gynecologist to confirm this schedule fits your personal treatment plan.
