What would the cause of spotting be while on birth control? I have been on a three month birth control cycle for 4 years and never experienced spotting, now I have been spotting for ten days with my period not due for two weeks. What would possible causes

Spotting. Spotting can be normal at any point while on birth control pills. It is usually due to an imbalance in hormones or missed pills or a change in time that the pill is taken. If the spotting persists you should be evaluated by your doctor to rule out a pregnancy and to consider a change in pills with a different hormonal make up. Take care.
