I've taken Climagest 1mg since November and am concerned that I haven't had any bleeding at the end of my pack for three months now. Isn't the final 12-day interval on the white tabs (prog'ne as well as estrogen) meant to ensure that the womb lining has a chance to shed itself somewhat? I may have stopped ovulating, but shouldn't there still be blood? I don't want to start a new month's pack in case I further compromise my endometrium. Any ideas?
