hi i would say 2 years 4 years max as by then the menopause should have taken over your birth control needs but do get blood test done each year as a hormone check this will tell if your menopause is coming. hope this helps you. good luck
how long be on birth controll pills. i'm age 53 years old 5' 2" 114lb non smoker and don't drink and do exercise. i just had my yearly check up few months ago with my doctor. he recommended i be on pills for few more years. i use azurette 28's still have menstration every months. do you have any comments?
