I am on the birth control azurette and I have been having rusty colored discharge for the past two weeks. (started mid second week of pills.) help?

Most likely break th. Through bleeding, which can happen on any pill, if u were my pt., I would do an exam, possibly cervical, vag cultures and an ultrasound, if ok, u can stay on that pill to see if the spotting stops or u may need a differnet pill, I personally do not like the generic pills, I see many more problems with my pts who take generics, my #1 pill is loloestrin.
See ur doc. Although no unusual to see some spotting or bleeding, I recommend visiting your gynecologist to make sure you are in the right birth control pill for you. Wishing you the very best.
