i completely blame cerazette for all the problems ive had. i havent had a natural period since coming off that retched thing 2 years ago - im now on my second course of medroxy something ( to kick start my periods).. i wouldnt go back on them if my life depended on it. i was always irregular before it but after it is litterally non existant and have a few friends with similar problems since being off cerazette... i wonder if this is medically acknowledged?
