I'm having menstrual issues, should I be worried? I'm on necon 1/35 (green) birth control and haven't missed one pill. I been on them for about 3 months. My dr. Has me skipping the placebo & starting a new pack because I've been having excessive, unexpected

That. That is abnormal to have bleeding for 8 days as well as having the excessive, unexpected, and long durations of bleeding. Given your history, please have your gynecologists reevaluate you. There is also a possibility that you might need a different type of birth control pill. If you develop increased bleeding, feel light-headed/faint, or have pain then you would need to be seen as an emergency.
